What a cute and fantastic foundation to a metroidvania style game.
I'll preface this by saying I wish there was some sound and music, being in complete silence feels really meh.
However the game was a lot of fun to play, I loved the pacing and tutorial and the interesting way you had the elements interact with the world was a lot of fun.
The little slime was really cool looking and I liked all the animations. I had a really fun time with this :)
