Does it play on a controller? cause I know Cuphead is much better on a controller so its easier to run away and shoot with. But I do see the inspiration. I did like the tapping to hover mechanic, and I think the difficulty more so came from the relative health differences. Like you hurt him fairly slowly but die fast. With Cuphead as an inspiration I can see why you balanced it that way since its a lot of quick firing low damage attacks that drain the boss over a longer time. I think more control over being able to constantly shoot and focus on dodging attacks would go a long way.
