fair enough, but it still feel so unsatisfying how your speeding along the level and with a matter of 2 to 3 seconds you take damage. maybe remove some certain hit zones? stuff like spikes and gas leaks? and after going through 2 more zones i highly recommend making the invincibility frames last just a bit longer. in sonic 3 they lasted for what feels like 2 and a half, maybe 3 seconds and that's perfect
