The True Slime King is a single player hardcore puzzle platformer with a focus on tight controls, challenging maneuvers, and mind-bending puzzles. All of this is achieved with just three buttons: left, right, and jump. Use your sliminess to stick to walls and cling to ceilings in order to avoid obstacles and reach hidden items. Whether you're a speed demon crushing records or you're just interested in progress through the story mode, one thing is guaranteed: you will die a lot in the process. But don't worry, you'll be respawned and back in the action just as fast as you can die.

So I was just sitting down playing this for a while, I really like how unique a lot of the mechanics are, the sticking to roofs and such is a really cool idea!

I'd say this is going pretty well, I just have a few recommendations to consider as you progress:
-Maybe use space bar for jumping/enter for selecting levels. With jump and level select both bound to the "j" key I didn't figure out how to do either until I went through pressing every button on my keyboard. Space is often used for jumping because your thumb is usually resting on it, I'm sure you have your own reason for using J so maybe just an option somewhere in the finished game?

-When it came to selecting levels I had no idea what to do, tried clicking, pressing lots of buttons, if there was a prompt to say "j" is to select that would be fine, but if you're not going to prompt you should probably try using keys people will think of sooner.

-With the blue slimes, the introduction to them feels a bit unneeded where it is, it's important to teach your player about them, but maybe in a section where it would feel more meaningful.

Overall this is looking like a great game and I hope you get to finish it because I'm sure a lot of people will enjoy it! Best of luck!

Thanks for your input! There's a lot of stuff I want to implement in the game and a lot I want to improve. I'm definitely going to take your comments into consideration.

I think the next thing I'll work on is making the the controls more obvious or include some kind of tutorial. I'm also going to implement custom key bindings at some point. I originally was using "J" for jump because the character originally had a few powers they could use, so I had them under "K" and "L", but now there's no real reason to have the default jump button be "J".

It's no trouble at all!

Yeah, even while you're in alpha states obvious controls or tutorials can be pretty important for the sake of testers. The alternate powers makes a lot of sense as to why you'd choose those buttons.

But yeah this game looks like it will become a really fun platformer as you continue development, I'll keep an eye on it to see if there are newer builds to test at later stages as well.
