The concept of using only 1 button is pretty fun and has good potential, but you unfortunately end up kinda disincentivized to go for cool giant jumps off the ramps before the final jump as you'll lose sight of the ground and potentially end up falling directly into an upwards ramp, killing your forward momentum. I think if there was a way to see the terrain below while high up in the air so you could more easily chain launches together, itd make for a very satisfying gameplay loop.
