This was fun. I really like the retro style graphics and it brought back some memories! I also really liked that you put some verticality into the level design to keep things interesting. 

A minor thing that made me restart the game on my first try was that the scene transition when i went through the first door made me think the game had crashed. May be it's shaders loading for the first time? A loading screen could help with this! I am playing in the browser in case that helps debug.

Other than that, i enjoyed this one. Good work!

I quite liked this game. It was a tough little adventure with nice theming (i liked playing as the little slime fella). Though i was very confused when mulm attacked as he turned red because usually in games characters turn red when THEY are attacked though its a minor nitpick. I also like the levels and doors, it was like metroid prime.

I need to get my hands on some REAL mulm soon!

I've always wanted to be the slime in a game. feels  good man. I really liked the level design and artstyle. cool outline on the enemies. nice!

I fell into the void :(

I like the structure of the game, impressed with how you put together the different areas which all felt pretty unique. It gave the game a nice sense of exploration, I had the feeling of wanting to discover all the masks and their abilities...

I myself was trying to create a game with a similar exploration vibe, and I even wanted to do the masks = abilities thing but had limited time to do that so instead went for just polishing the basic combat more.

The cactus guy was hard to kill! I almost gave up there. After I got the balloon mask I didn't know which direction to go from that upper doorway, that's how I fell to my doom!

Great job overall, biggest critique is I didn't hear any sound or music at all, that would have added a lot.

Loved the art style of this game and the slime creature was amazingly wobbly :)
