Loved the art style. Liked the gameplay twist at violence, but that level was a bit too difficult for me. I couldn't figure out if there was any strategy to dodging the knives, or if they were just random. It'd be cool if the knives were tied into the level design somehow, so you could predict where they might fall.

I really like "Press twice to quit the game" , how to make that?

Nice aesthetics, it feels really polished. I did not like how easy the game was though, it felt more like a walking simulator (or digging in this case) then a actual game. I got bored of the simple move down in a straight line until you finish the level without hardly having to do any corrections and the repetitive head smash sound. So I did not bother to see the actual end, I stopped half way in the game.

Not finding a problem. Transition was smooth from Limbo, Lust and Gluttony. Will  let you know more  when I finish the full game.

Can any WINDOWS user confirm if the game breaks when changing levels (when the tiles change color on the level and the player starts to fall)

Grcar Games is having this problem and I can't reproduce it
