this is a pretty good puzzle game with i think an interisting presentation in the form of a fake os, and some really clever and fun puzzles, altough the main issue is thats not always the case, the puzzles can vary alot in quality, some puzzles are genuinely super clever and fun, others are kind of way too easy, and some are just annoying or super cryptic to complete, the game does have a hint system but there was one puzzle that i got stuck on and even when i got all the hints for it i still didnt know what to do because the hint literally didnt make sense (i think it was poorly translated), this was a majorly annoying part in my playthrough, but still ignoring the bad puzzles you will get a fun and quite unique puzzle game here
