v104, the second map doesn't load.
The v102 worked ok.
I'm just falling down indefinitely. Doesn't really seem to be stuck in loading since I can access the menu with no problem, restart, quit, etc... I think it's similar to when you forget to include a map in the build of the game and then try to load it. I was gonna check the output log but can't find it.
That problem is caused by the game failing to save. Possible reasons are that the Saves folder is set as Read Only or is in a Read Only directory, or that you're attempting to play directly from the .zip file.
I've since added a warning screen that tells this to you when the game starts if it's unable to save or load and lets you progress with saving disabled if you want, so that will be in 1.05
So I downloaded the steam demo, the save problem is fixed. The main problem I have is the game becomes slow when it drops below 60 FPS, mostly in large rooms and room with grinders (or maybe it's the glass floors). There aren't a lot of games I can run at 60 FPS, but some are ok even at like 30 FPS, yours go in slow-mo, some games get input delays, which fortunately doesn't seem the case here, but it makes charging weapons awkward.
