Thanks for taking a look! Really happy for the feedback. There are a lot of great ideas in here that would be simple to try out, so I definitely will.
the control scheme could use a bit of love (I kept trying to use A/S to rotate)
Could you elaborate on this? Am I right that you were controlling throttle with the arrow keys? I wonder if I should abandon one set of throttle controls and pick either arrows + AD (or AS or QW or something) -or- WASD + arrow left/right. What sort of scheme would you find ideal?
let the trick affect the boost - either max speed or duration - a triple flip is just cooler than a single one
This is happening, but it's unfortunately really invisible to the player. The duration of the boost is related to the number of flips, with a bonus if the trick isn't the same as the previous one. Doing a new trick extends any remaining boost duration. I think I probably need a boost timer, and to explicitly show a +whatever seconds somewhere when you do a trick or something?
I'm slightly skeptical about stacking velocity, only because it seems like it would make it harder to design levels. But getting a bit crazy with it could be fun.
