Unless I am blind, I could not find an option to adjust volume. The sound was a tad too loud for me. Good polish, i appreciate it a lot that you directly have a tutorial and a prompt to force the player to apply directly what they just read (hopefully at least). The sky racing was fun but the gravity felt so heavy. Whenever I went up, it was so difficult to accelerate. With upgrades it got better but if I am being honest, I am still not too sure how the collision boost or the arrow boost works exactly. The collision boost more often did not help me because the only collisions i had were with obstacles that pushed me back further (did not help that the momentum got also increased there haha). But the main gameloop felt not too bad. Reminded me a bit of Kirby Air Ride Top Ride mode. Which is a good thing.
Visually it was incredibly pleasing, whoever made the art, well done. Fits well and especially the character animations are very cute. I already mentioned everything about audio that I wanted. Also its a clever trick to make people comment haha. I have to remember that for my own games that I publish on itch. Mine was 4:28
