Further accumulated thoughts:
- I think part of what rubs me the wrong way about how the down-boost is currently implemented is the ways it restricts your control. It feels like the counterpart to the normal boost, which you can activate any time you have charge, letting you use it for anything that a sudden velocity change could be helpful for; avoiding Bae, restarting a stalled flight,
catchingdifferently missing an airborne power-up, etc. But you can only use a down-boost if you are at a fairly specific altitude and moving up, meaning that it's basically useless for anything except recovering a power-up that you landed slightly to the left of, or occasionally dodging Bae if you know you're going to hit her at the right time and can get the right angle. And that uselessness isn't a factor of the down-boost, but of when the game lets you down-boost, for no reason beyond the game designer deciding you shouldn't want to down-boost when you're not going up enough. - It would be neat if the game pointed out certain achievements you re-achieved during a run. Not the basic ones like Super Glider, Rocket Power, or the Monopoly achievements, but the ones that feel like achievements. Might help some of the runs that didn't achieve anything new feel like they achieved something.
- To be clear, I was serious about IRyS's volume changing with altitude. That wasn't just a joke. I think it would help "sell" when IRyS gets really high.
