This feels like a very obscure game that a very obscure game studio with a 30-letters-longs (or longer) name might’ve made during the PlayStation 1 days.
Unfortunately, you not only captured the good aspects of this kind of game (Graphics, Sound Effects, and Artistic Direction), but also the poorly-aged controls:
- It should be possible to invert the camera controls for both axis individually.
- It is unreasonable to perform the Mid-air Jump once it’s unlocked: It should just be a second press of the Space Bar, no additional Control key.
- The camera should not only be rotatable with the Arrow Keys, but also with Mouse Movement.
