Damn its a good game! It made me scream and smash the keyboard at level 7 8 10!
The graphics and the beats are a good combination. They make the game have the vibe of 1980s arcade! The battle is intense and addictive, make me wanna try it again and again.
If I have to be picky, I would say the hit box still a bit off, especially for the heart and the dog, I am not saying the hit box is wrong, but making it more generous gives more possibilities to the game.
Also, a minor issue, the character and the UI are sometimes clipping.
I see so much potential in this game! Maybe in the future, this will be a complete arcade game. Increase the difficulty more slowly. Right now there is a big jump betweem 6 and 7. And I don't think this game needs procedural generation at all. Every level should be hand tunned and challenging enough, but not impossible.
More juice, more enemies, and more levels!
