Graphics are simple but serviceable. Got to the boss twice. The game appears to have returned to title without prompting shortly after I accidentally glitched down through the boss elevator and was trying to die before then. I will likely go back and try again later.
I also got on a weird angle at one point. I can send you a screenshot if you like.
This has some promising combat, but I would work to simplify controls if you can. There were some personal preference things that were bugging me but really there should just be fewer buttons to know.
