Neat to think about conceptually; a character imagining themselves as a visual novel character in a visual novel as a grounding mechanism is cool in a "Haruhi" sort of way. Sadly nothing about the game is exceptional, and it is far too short to leave any sort of emotional impact as I played it.

Additionally, it should not have Steam achievements. No game based primarily around a narrative should have achievements. Having any kind of completion marks in a game like this makes the narrative choices after you beat the game less fuelled by curiosity and moreso by that urge to easily 100% the game. If classics like Undertale and OFF can call into question the player's agency and choices in-game so effectively without achievements, anything should and could try to follow.
