Thanks! The controller itself has controller support, but not the gui since I didn't have time for that. A friend played it on his controller and it seemed to work well!
The controller acceleration was very customized to what I wanted, but yeah I can see it being a bit wacky to others haha. I'll probably tweak it post-jam when I can update the game again :)
Also there is an options menu! It's in the pause menu (tab or esc (esc on webgl might need to press twice)).
