Thank you Kwiper for your feedback, it's really helpful. Somehow I find the jump attacks satisfying except for the dive attack, so maybe I'll add a variety of aerial attacks to keep the player in the air and probably executing the dive with a button combination would be better.
As for the level layout and enemies, I simply lost precious time. The original vision of the game is way better than the current outcome and would be happy if you could come back next time I update it. Thanks again for playing! :)
