It's cool to see a TIC-80 release. Thanks for that!
I enjoyed the graphics and the combat was interesting. Nice upgrade system and general game loop.
I did struggle a bit with the perspective. When being facing 100% up to a wall like that it's difficult to orient yourself if there are exits to the left or right. Other times it looked like there was an exit to the side but when turning it wasn't. Other than that, good job :)
