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 yet ANOTHER long-overdue version of Ex Vitro!

While I wasn't able to completely finish everything in this version, I'm determined to power through the rest of the year and get as much of it done while I still have my health. I expect that there will be one more major update after this, including the final phase of the last boss and a few endings.

It's hard to believe that when I started making it, Metroidvanias seemed like a bit of a niche genre, and now the internet is saturated with all sorts of variations on the formula. So, I figured I might as well get this monkey off my back and inject one more Metroid knock-off into the internet's well-stuffed gaming community!

Updates in 0.90

  • New main character graphics and animations.

  • New charging effects for all beams.

  • Screen scaling enabled.

  • Optional tutorial messages added.

  • Post-final boss rooms added.

  • Final game stats screens added.

  • Simplified or removed many 'crawling puzzles'.

  • Minimap has a glowing effect when the current room has a hidden EMP item in the walls.

  • A small animation has been added to the character when the EMP is ready to fire.

  • Some enemies have new charging effects before they shoot.

  • Some bosses have had their health reduced.

  • Credits screen added.

Huh, not sure what the deal with this is. Here's a thread with some solutions, looks like there are some other Game Maker games that had the same issue: Forum.yoyogames.com

I tried reinstalling VC++, (newest and oldest), restarted PC, tried running without any other programs, but it still gives me the same error.

No idea why, everything else works fine on my machine, even other game maker games. : (

Bummer, sorry to hear that. I'll have to borrow someone else's PC and see if I can get the same error to pop up. Not sure why that's happening at all!

Try this: Locate the game .exe and open its properties dialogue, click on the security tab, then the button to edit user permissions. Check 'Full Control' for every user and group and saved. Seems like Hotline Miami had a similar issue, I'm just looking through various groups to find a solution.

No, didn't work.

It seems wierd that would fix it though. Are you sure theres no coding error/accident related to the mentioned "object oEMPStarFlash" in the game?

Maybe the game failed to properly compile / publish in game maker when exporting the exe or something?

Hmm, I'll have another look, but I don't think this object uses any particular external resource. Maybe I'll try to build a new executable without that object and see if a similar error pops up. The joys of Game Maker! lol
