It has roguelike elements similar to Slay the Spire, but that's that's not what I like about it.
Mild spoiler
That's just a misdirection for what the game is actually going for, in a similar way that the "Dating Sim" description is a misdirection for Doki Doki Literature Club.
I will say it has a distinct ending, unlike Slay the Spire.
It's a great game to go in blind for, so I'm not going to go into too much more detail.
I searched around the room, completed few puzzles and I got the film roll (which I'm guessing is used to win the game, since the slime says to defeat "him"), but I'm not seeing anything else.
