Honestly, not a bad game.
Very straightforward & simple, but I can see potential to really expand on this if the devs so choose to.
I did however stumble onto a game-breaking bug I'm not sure how to replicate. And it's actually double-edged.
The bug basically makes your character completely invisible to mobs, and they all ignore you entirely. Bumping into them does nothing (haven't tested if activating the Mimic maybe resets you but I went down 20 something floors and didn't find a single one)
This bug is bad/good cause on one hand you can explore freely without fear of the entities... on the OTHER hand... if you're looking to unlock the gallery, this can be a problem.
