WOW Hahahaha this is so good lmao. The game is so simple and yet, it is addictive. The atmosphere you created with your art style and the music is superb, they really compliment each other to set the tone of the game.
The minor thing is, the game is simple to learn, but there is something in that level 2 that will stop you for a little bit to figure out what to do. Minimizing the instruction is good since it gives a rewarding feeling when the player discovers how the game works, but the way it was presented is kinda not smooth on that specific level.
