There're a lot of good things about this game! I love the visual and effect so much, quite minimalist but work wonderful with the game! The gameplay was very fun and easy to understand, I thought the mini-map was a nice touch :D
For some constructive feedback, I personally think the fuel bar is a bit too much, I didn't think the game need it, and the ball collide with the collectible is a bit odd and maybe reduce the number of collectibles in one level would be nice :))
But overall this is a very cool game! Great job!!
