This game is quite a bit like the old Unnkulia games: snarky or rude to the player at times, obsessed with unfair puzzles, filled with little 'male gaze' comments about women, arrogance about religion and philosophy, and full of 'goofy humor'. I didn't really like it.
It is big and mostly polished, but the puzzles are pretty opaque, more of a 'look how clever I the author am' than 'look how clever you the player are'.
You spend much of the game travelling back and forth through time and your own mind.
