A really good puzzle game. Great animation. A few things:

1. As others have already mentioned, a few platforms blended in with the background of the game.
2. You could potentially add some lore to the game based on all the keys and all the player collects.

Good game.

Nice game. Liked the slime animation and art. Good job!  

This was such a fun puzzle game - the slime is so cute.  I liked how the challenges got increasingly harder as you progress.  Something you may want to look out for is making it clear where the player can land and where they cannot with more contrast.  I noticed in one of the levels the platform I could walk on blended in with the wall.  Keep us the great work! Would love to see this game evolve into having more levels and a story.  An added challenge of time to get out and showing players progress via a level map might be cool too.  Will keep an eye out for more games from you!

Definitely fun, would have liked the platforms in the eariler stages to stand out a bit more, completly missed them until I landed on one. 

Slime animations were adorable, didn't get to finish unfortunatly (playing on my break at work) but I kept going for longer than I meant too, great game!

The amount of levels and puzzles is impressive and the slime is well so animated and cute!

Other than background music, the biggest problem I had was telling what was part of the background and what's not. Certain platforms blended too much with the background.

Overall, great job on this one!

Great job! Really enjoyed playing it! Nice animations, simple and intuitive puzzles concept, attention to nice small details and you created already a lot of rooms: already a quite complete game! 

I encountered some possible little problems (maybe you  already know about them, and they did not reduce my enjoyment of playing!): 

1. in a room clicking fast enough JUMP and INTERACT you can trap yourself (maybe is intended, but had to restart);   ended up in this state:   
2. in the next room (of 1.), over and left to the first button (almost out of the window) there is an invisible small platform (from which jump doesn't work)
3. Sometimes seems like I click E, hear the sound but nothing happens, and I had to click again (I don't understand if it has a function/meaning or not)

Anyways great game!  Keep up the great job!

The way you animated the slime was so adorable! The puzzles were nice, the only issue I had was some of the platforms at the start blended into the background and were very hard to see.  I did not notice this as much in the later levels, so it gets better or I got used to it. 

Nice animations and puzzles overall!

This was really fun! I loved the little animations you gave to the slime & the jump pads were a nice touch. Some background music would really round this out.

This was fun. It was kind of relaxing not having music but next time I would suggest having some music in the game. Mellow puzzle game, I had fun playing it. 

Pretty interesting! However, I wished that the character matched the other assets or vice versa.

Nice one! I like the puzzle element. I personally would find the game to be tastier if jump physics were a little more realistic, ie a tiny bit fast so it felt more natural but its not an issue. 

Really cool art! The concept is really cool, the only issue I have found is that in the first levels you don't really need the things that there are, I think it's... "overly complicated", but other that then, I enjoyed playing it! Good job and PLEASE, release a full version!

Good one :D

I realy liked your art :D
