A platformer/shooter with emphasis on exploration, ala the Metroid series. Development began as a test to see what I could do with Game Maker, and expanded from there.

Here is the latest long-overdue update of Ex Vitro. My goal this year is to finish this version of the game, so I can finally migrate to a better engine (*cough* Unity *cough*). While I've learned a lot using Game Maker, I think it's severely limiting the things I want to do. So, I've decided to cut short some of the bigger plans I had, and save them for the next generation of Ex Vitro. Essentially, the next update will include the next phase of the final boss, a conclusion to the story, and new character art.

Download here: link

Included in this version:

- Final Zone (note, this area is heavily scripted so I would love to hear any feedback on bugs or glitches!)

- First phase of the final boss (more complex scripting than the other bosses, and quite a different type of battle as well. Reminiscent of a certain boss from a certain Nintendo series, but hopefully unique enough to stand out)

- Final jump upgrade (again, reminiscent of a certain item from a certain series)

- Rewrote some data logs to better fit what the conclusion will lead to

As always, send me any bugs or glitches that you come across!

Just finished playing the demo. I friggin' love metroid-vanias and Ex Vitro is just what I wanted. Nice music, great graphics and very fluent gameplay.

I entered every room thinking "I hope it won't end here since this is a demo...", but you've really made a large and fun demo. The only thing that made me upset is the first weapon we had; after getting the blue one I've never again used the first despite upgrading it. All others are awesome though.

Oh and just a little thing I've noticed; the "pipe-ways" we are passing through, at some of them there's a layering problem with pipes and particles. At some parts the bullets travel "above" the pipe layer where it should travel "below" of it. I believe it happened at that yellow area with lively yellow slimeys.

Great game Adjuvent, well done. Even the demo takes your time but it worth every second.

Solid start so far! I have started a similar project in C# and wish I was a decent artist like you! You need game pad support! Not only is your foreground nice but the backgrounds you have created are simple but work well. Great start I hope to see you continue this.

Hi, I really enjoyed playing the beta! I'm always on the lookout for games like this. I have some feedback for you, hope you don't mind:

The movement controls have some weird acceleration on them that makes it difficult to predict. If I had to guess, you did this to allow for small movements with a digital control scheme (the keyboard WASD). But small movements didn't feature heavily in your level design. I think you could resolve this issue by continuing to avoid the need for it in level design and eliminate the acceleration on movement.

Most enemies in the beginning of the game are in areas that can't be reached by the player, at least not right away. When they drop powerups, they are generally unobtainable. Metroid Prime had an interesting way of solving this problem: when you charge up your shot, it draws powerups in to the player. Another way you could handle this is to give the powerups gravity to make them drop down. Just a few ideas on how to solve this issue that frustrated me when I was low on health and could see the health pickup, but couldn't get it.

The level design progressively gets better in the beta, but it starts off weird. The starting area is really barren, which makes sense if you are teaching the player how to jump or crouch or shoot in a safe environment. However, the length between "teaching moments" is really long and it feels like I am simply walking forward, waiting for something to happen. I think you could cut out entire areas and make it more interesting.

That's all I have for now, keep up the good work! I'm looking forward to seeing the new character direction in action, it looks really cool!

Overall I liked the demo. I agree that the datalogs should be in by default -- I didn't even realize that's what the option referred to and played through without even knowing they existed. I only have two gripes about the game thus far. First is the pause between shots, which feels a little long, but being able to play with the second gun longer probably would have helped that. Second is the kneel and crawl mechanics -- they feel a little clumsier than Metroid's ball form, especially when trying to jump and crouch at the same time (although Half-Life was worse about that).

Overall, quite looking forward to this being completed.

Thanks for the positive feedback!

Yep it's a brand new release! I've been plugging away at it since the summer, so it's nice to finally have some people playing it.

Probably because it was release just today? hurr durr.

Just downloaded and played the demo through. It has a very super metroid like feeling to this game and so far I love it. I also like the story and universe, really great stuff. Although I'd be cool to know who are you controlling and whats your mission.

Also I'd recommend having the datalogs be a default part of the game, but have them seamlessly blend with the world as computer terminals and such that you can interact with same way you do with the current datalogs, and the computers screen would just go dark after you read the message.

Enjoyed it and will track for updates :)

Thanks for sharing your thoughts, and I'm glad you like it!

Yeah I was aiming for a Super Metroid feel, so I'm really glad you felt it achieved that. I plan to eventually have a cutscene at the beginning, that should hopefully explain a little more about the situation. But I think I'll keep it somewhat ambiguous because I like mystery :)

You're the first person who's mentioned the Datalogs! I was debating whether to make them default, but decided on optional because I wasn't sure if my writing was any good, and some people may prefer to not have walls of text appearing in the game. What did you think of the writing itself? Corny/cheezy, etc? Your suggestion is definitely something I'll consider! Thanks for following!

I really enjoyed the texts in those Datalogs. Some logs gave interesting emotions, especially those that were about human brutality over aliens and the grim reality of galactic conquest. Other logs added some random humor, like that log about overlapping project names. All were awesome and really enhanced the atmosphere in the game. It felt like there was more to the world than just being a flat shooter. All those little details count and you did them well. I like the realistic vibe in it too.

Btw, is there any particular reason you made the beams be seperately selectable? You could simplify it by having just one beam that upgrades as you go since they're not really that different from each other. Super Metroid did this and you only needed to switch to other equipment if it was radically different in some way (missiles/bombs that use ammo, grapling beam that is a situational tool/weapon ect.).

Great! Maybe I'll consider putting the Datalogs in as a default if there's a positive response to them. I had a good time writing them, even if some of them get really grim and unpleasant! But I figure some humour in them would balance that out, so I'm glad you liked the mixture of emotion.

Hmm, as far as the beams go, I think the original plan was to just have one upgradable beam. But I felt that it got kind of boring just vaporizing everything with the same shot, so I added in beams that had different effects. I agree the first two are pretty similar, but some of the future ones will have really complex and powerful abilities, and it would be impossible to combine them.

For an example, if you've got the Entropy Beam in the demo, you'll see what I mean when you combine the charged and uncharged shots. I like having interesting combo effects like that, so future beams will have similiar ways of working. Also, I'm going to have each beam be individually upgradable, so hopefully that will further differentiate them!
