played for a bit, overall a very nice demo, I'm sure you've heard about this already but you can keep increasing the character's stats infinitely by keep click equipping items, also can't equip box cutter.
it's not clear what exp does, but I'm sure it will be explained in the full game.
also it's kinda strange that the mystery just straight up ends without any conclusions, like fighting a boss or any summaries. but I'm sure it will be included in the full game.
another minor thing is fighting the monsters, since I don't get the meaning of exp, right now it's always better to escape than fight, maybe you can gain items from it but I don't remember that being the case.
