Really impressed that this is your first game! It oozes style, the art and music work really well together to give exactly the vibe you're going for I think.
The gameplay is lots of fun, I adore physics-y type gameplay, and the inertia and bouncing gives just the right amount of challenge in controls for it to be fun for me. The difficulty curve is a little all over the place, it gets harder and easier seemingly at random - but that sort of thing comes with experience to be honest, and it's not a deal-breaker.
Looking forward to seeing things you make in the future, I've given you both a follow on itch.
