Pretty cool prototype that I'd love to see more from! At the moment, the game seems a bit too slow to get going: takes a long time to build-up money to be able to actually have some control over your flight with power-ups, and then they are only one-use and gone, leaving you to build up more, unfortunately slowly and randomly. I like the goal system, but they didn't seem to reward anything at the moment once completed: if they did, that'd be a great way to give the player some orbs and get them to the fun stuff quicker. Having said that, it would be nice to have the player control their experience a bit better all the time: maybe a more zoom-ed out camera when going fast so you see ahead and plan manuevers, along with the ability to always slightly manipulate your movement even without items by rotating in certain ways (or maybe just replenish items for free)? There's a lot of ways this could be built on and I'm looking forward to it: hopefully my suggestions help but it could be the core idea that the game is intentionally supposed to be a bit random and not player skill-based, in which case you can disregard my rambling!
