Interesting game, I had fun. Here are my comments:
- lava being an insta-kill feels a bit cheap with the character being as fast as he is
- I think I got the items figured out. Sword, Heart and shield are obvious but it seems hourglass is move speed and gun(?) is fire rate? It was a bit hard to tell the difference before and after so I wasn't quite sure. Also if the gun is actually a gun it's kinda hard to tell.
- Is there any compelling reason to pick one room over the other? the rooms all seem to be randomly generated on entry so it's not like I can create a mental map of the are in my head.
