Okay, this game is ♥♥♥♥ing awesome.
It's the kind of game you play once every few weeks, but for the rest of your life. Great if you randomly feel like immersing yourself in a richly aurally-textured half-axon half-multiverse tunnel with a pace ranging from narcoleptic to highly spasmodic.
The actual goal is collecting glyphes embodying tiered concepts, with a final one marking a progression we'll get back to; all while avoiding obstacles as your speed slowly increases with each level.
For instance, level 1 is the nasal ganglia, with concepts such as "peculiar insight" or "nervous laugh" and the final glyph being Awareness.
The gameplay also involves the ability to, holy ♥♥♥♥ing ♥♥♥♥, SLOW DOWN TIME
. The game really has a particular relation to time in general, as you slow down the sound environment as well and pausing temporally stucks you in one audio piece. Said pieces otherwise naturally flow with the game.
While all golden glyphes make you "progress", and the general goal is to collect everything, the game has one and only one condition for winning : collecting the very final glyph, Unhumanity. Completing a playthrough rewards you with the ability to choose an in-game avatar from a variety of monsters. As for what happens when you miss the glyph... I'll let you see for yourself.
So in short, exceedingly fun, love the overall feel of the game, EXTREMELY underrated on steam. It's one of those little games that have a special place in my heart. Maybe literally given the environment.
