My gamepad is cursed. x) On a chrome based browser, thrust is not detected, and on Firefox it's on the left trigger. (it's not the first game where it poses issues, so it's not your fault)
Okay, so I find the concept really clever and on spot with the theme. There's an interesting balance between collecting stars and trying to improve its time. But I found the execution really frustrating. I thought it was first because of the mouse controls, but even though the gamepad improved it a bit I still had a lot of troubles. I think it comes down to two things. First, the feeling of progression wasn't there. It feels slow at start, and even after several speed upgrade, it's still slow at the end. And my previous ghost seemed like a testimony that, yes, I wasn't going any faster! :P Perhaps it was just an impression, or a lack of feedback, but really even with powers like boost on collision or arrow boosts, I felt I was sluggish. And secondly, I'm not a fan of the level-design. Especially once it gets harder. Moving obstacles that completely blocks the track, forcing to wait until they retract… Boost arrows that goes right into a trap… Targeting bomb placed after a straight line that you can't see until you hit them… This all seem unfair, and going against the speed improvement of the game. How am I supposed to go faster if I also have to be more careful? The boost on collision also quickly gets nullified, as the tight turns and narrow spaces doesn't seem to take account for it. It just made me bonk on every walls.
So unfortunately I didn't have a really pleasant experience with the game. But I wanted wish I had! Its visuals are great, the sound just makes you want to play again. And the concept is once again really cool, I think it's a solid design. Even the physics is actually fun to master (at least on the gamepad). It just doesn't get off, for the reasons I mentioned. But it's a jam after all, balancing is one of the hardest task. It's still incredible that you managed to pull that off during the jam!
