Oh hey, nice to see it back.
Mode-A:
I reached Phase 10 in this attempt. I could've gotten over 170000 points if I didn't mess up the first two bonus challenges.
Words of advice: Beware of the bumpers from Phase 7 onwards, they can screw you over. By the way, sparks are instant-kill.
Mode-C:
Could've been 30000 if I didn't stupidly hit that spark at the top of the screen. It's worth noting that in this mode, collecting a balloon gives you 300 points, while getting a bubble gives you 500 points and a temporary screen freeze (you can still fly around, though). Another thing to note is that you get 100 points per half-ish second except when the screen is temporarily frozen due to collecting the bubble. Just some scoring details, nothing more.
