Neat game with a retro aesthetic. Art, music, SFX all complemented each other nicely.
The progression system is really cool too. I liked how you worked each new ability/powerup to the fight you had just completed. Bosses all felt unique and had some character to them.
For improvements, controls are a bit weird. Something like WASD to move, left click attack, right click spin, space jump attack, Shift or F for teleport attack would make more sense imo.
Well done for submitting in the timeframe!
