This game is pretty quality, but definitely needs touchups overall.
I found myself often not knowing what to do due to a lack of guidance. Getting stuck for 10 minutes trying to open a packet of Ramen or taking until Night 15 to realize that headpats reduce wakefulness definitely isn't fun.
The game's biggest flaw, in my opinion, is the skill system. Every time you complete a skill check you're given skill XP, but failure gives you nothing, and this lead me to feel as if I shouldn't try at all during most skill checks, and when my skills got high, I was given boatloads of XP that I no longer needed.
The central gameplay loop is thrilling and creative, the tension of what you're doing is really palpable and you feel real panic at the prospect of being caught. I wish there was more content for suspicion as it changes, but overall the night system and Yuna interactions are great.
7/10 with potential for a completed version to be 10/10
P.S. Game crashes if you press the study button while you don't own any books and then try to go back.
