Graphics-wise, it's perfect. I wouldn't change anything.
The gameplay has some problems:
- The controller's d-pad input is poorly made, it's almost impossible to walk with it (using ds4windows), the joystick itself, however, works fine. (Note: if you're using Input actions, try to assign the dpad to the same actions as the joystick).
- There are too many ranged enemies, from the levels I played it was around 50% of the enemies, resulting in dragging out the level or getting killed instantly. I would suggest either reducing to 25%~33% or adding some sort of (rare) healing item (maybe 1 hp per level?).
Other than that it's pretty solid.
The sound was well made except for the music, which was weak. Although for a graphics-programmer team was reasonable.
