Neither a good horror game nor a good Nintendo GameBoy-style game, Ptolomaea feels more like a heavily-stylized and otherwise typical horror game with crypticness for the sake of being cryptic and unearned jumpscares.
Honestly, this game would've worked better if this were a game for the GameBoy - you can absolutely do this sort of game if you know what you're doing...though TBF that likely would've been undoable within the time limit of the game jam this game was a part of.
