Playing this right now. I'm hoping to actually finish all of your content this time, now that I finally have some time to relax.
The art is great, music is comfy and very fitting, animations are great. Enemies are very satisfying to kill. Difficulty feels just right - really hard (for me) but not unfair. Every encounter feels tense. It's nice.
I discovered magic entirely by accident. I picked the sword and staff as my starting weapons, but didn't realize the staff gave me access to a spell until I looked through the menus. Fireball is cool and satisfying to use. Haven't used any others yet.
The sound skellies make when you kill them is perfect. Hearing the crunch is like music to my ears.
I moved onto floor 3 and alt tabbed to write this. When I tabbed back in, I think the game was still loading, because Towerguy wasn't anywhere on my screen and I couldn't move or open the map or anything. The usual loading screen wasn't visible. After a while the "Press any key to continue" screen popped up and everything started working again.
The only nitpick I have (had?) was that the map didn't have an opacity slider, but you or somebody else informed me in the thread that +/- works for that. I'm still playing through it, so if I have any useful feedback I'll edit this post. It's genuinely really fun though, and it's hard to find any serious faults. I'd buy it.
Edit 1: Trying to reproduce and record the loading screen bug. Saves also weren't working, but I died and restarted and now saves and the loading screen(s) are both working again. I'm gonna keep trying to break it to see if I can get a recording though. Also, I used a potion during a loading screen while pressing every button on my keyboard to see what I could break.
