Very cute game. I like the slime or leaf or whatever that little guy is.
I think the fade out to black for the screen transition is a little bit too slow.
The gameplay is a pretty simple platformer. I think the concept of short quests is pretty neat.
The story is nice and pretty random (in a good and funny way) towards the end.
I like your interpretation of the theme. I rarely see a game that interprets the theme in a morally good way, if I can describe it like that.
The art is pretty good, no complaints about it.
The audio is pretty nice too. I like the BGM and how it changes between level. The SFX are also pretty good and fits with the game.
