@Gets Hey . . . I thought this was the QB64 game jam, not the SNES game jam.
All jokes aside, wow, your game looks
really good. Granted, I know myself how easy it is to just import nice graphics with _PUTIMAGE but this is the level of graphics I'd rather see in a qb64 game than things made with circle and line statements.
The scrolling background is nice and I like how the game stops progressing until you clear off all the enemies.
Your game also makes nice use of the anti-gravity theme. It definitely takes some timing, but I did like how you could stop your anti-gravity ball in midair and jump into it to jump even higher and punch flying enemies.
Controls for the most part are pretty good (I only played with keyboard) -- I occasionally got jump and fire mixed up.
My only real suggestion for improvement: Sometimes it can get a little hectic trying to manage your anti-gravity ball, dodge enemies by jumping and positioning oneself correctly to punch other ones. Maybe simplify the anti-matter weapon since that takes the most concentration as one always has to consider if the projectile is still moving, stopped or returning.
Good job! It looks and plays very similar to a late-era NES or early SNES title.
