I have some things to say about this game:
First: The bosses designs are EXCEPTIONAL, it's truly GREAT. I loved it. The character designs are also very lovely and charismatic, the blend between pixel and 3D can work but it might need some readjustment. I really wanna see this game thrive because it has so many sick ideas, that's why I'm writing this.
2 - The balancing is not in a good state. Normal punches do 10 damage and have 0 range, as opposed to the shoryuken attack dealing 100 damage, with no drawbacks aside from being slow to cast. Not only that, you can hover in the air and always land the punch. The player health is gigantic. I didn't bother to actually avoid bosses hit aside from some of the snake attacks. How every fight played out was basically spamming the special attack and tanking every possible hit of the bosses.
3 - The scenario is a bit tilted to cover the ground area, but the sprites are in a complete sideview, so this make them appear flat. I suggest making the scenario in a perfect sideview and see if the sprites fit better. Also in the 2nd fight, the buildings make me a bit dizzy, they go so fast and the colors are very similar to the sprites. But I absolute love that idea of the moving scenario and buildings, and the whole fight has everything to be a cool fight.
4 - The snake boss is broken in a couple of ways: The laser beam I can just be behind the mouth, right in the neck, as it theres no collision, and spam special attacks and freely punish. Maybe add some collision there? And finally: When I killed the Snake the game broke. It came back to the right side of the arena and froze, leaving no way for me to proceed.
I'm not sure of how aware you guys are of the issues. But everything I said comes from a place of love. This game has SO MUCH potential and I want to see it's glory. Please take what I say in consideration. All that said, I had fun playing this game. Good job everyone.
