Good stuff! Artwork was cool and collecting stuff was satisfying.
To offer some feedback, I think a possible way to enhance the looping gameplay is to make the loop itself more dangerous, as I spent most of my playthrough in a single loop and it only ended when I manually left the loop. Having more enemies that can end your run against your will would make exploring more tense and exciting. I also found many areas where a room had a locked door, but had another opening I could walk right into, and I was sometimes able to walk through the locked doors entirely. No big deal though as this is a jam game and some bugs are expected!
Best of luck to you!
