Are you using boilerplate UI? Your presentation needs an overhaul. I open up the game and the first thing I notice is I can't use a mouse to select, then that the options menu is ordered with q and w instead of left and right. I start the game and am assaulted with a bunch of disembodied icons, press right and am assaulted with more icons and controls of things I don't know. I start a dungeon and press arrow keys 3 times while icons shift around randomly and apparently I have cleared it? And then there is a bar draining and I just mash up with no idea of what I'm doing until I win.
After that I go back and find the tutorial was not the default selection. Then I play it and... it's actually fun. Props for the adaptive music, too. The normal dungeon is still a bit janky, though, and there are still way too many things I don't understand after the tutorial.
