It's got a lot of clever puzzles, most of which involve cheating geometry, invisible staircases coming out of nowhere, and having to not look at things to make them work (or keep them from working). Then, the block puzzles start, and are infuriating because it turns out most are unsolvable until you upgrade your gun which involves finding one specific place in the stupid fucking non-euclidian maze that isn't even behind all the puzzles or anything.
Yeah, I got frustrated and watched a walkthrough, and guess what? 99% of the puzzles are completely meaningless and unnecessary. All they get you is little 'signs' that are basically exploration badges.
I also noticed a timer counting down in the corner of the start room. If the game resets itself when that reaches 0, I'm uninstalling it because fuck that shit. Seriously.
I really need to stop trying to play these avant gard games because I never like them.
