God, this game is so pretentious.
The author's idea of a challenge relies on grating tests of the player's patience. Be warned, you will grow infuriated as he throws pixel-perfect reflex 'puzzles' with a bare-minimal tint of stimulating mental strategy. Don't even get me started on the insufferable excuse of a narrative, written in a style of an angsty adolescent masquerading his tripe, nihilistic shower-thoughts as deep insights into the human condition.
The author is incapable of storytelling. Go play The Binding of Isaac, a superior game he made in a much more mature state.
