I love the retro vibe! Good game; feels very nice. I had a bit of a hard time apprehending the controls, and it is hard to use the dash properly since it stops if you release the key before having chosen a direction. Well done :)
Maybe indeed. Or to let the player release the Z key once the dash is fully charged without canceling it, at least for a short period. Just enough for it to not be frustrating if you release too quickly the key before choosing your dashing direction.
