Decent for as far as I got (~level 2?) but it feels like a LIMBO rip-off. It's one thing to be inspired by a great game and have that inspiration shine through, but this plays a little too close to home for it to feel authentic and original.
The music is nice at first but gets very monotonous quickly. It'd be nice to give players the option to mute the music, to mute music without muting sfx, and to also make a menu available to access in-game without completely ending the game. Didn't realize that that's what would happen when I clicked "menu," and now I don't want to play the game again.
