Oh my, this game gets real quick, real fast!
I love that you have a working leaderboard, and the gameplay feels nice, I feel like the speed might scale up too quick, though? That's a bit of a preference i guess. There is one thing that i'd improve though, since the game can get so fast-paced, you can missclick when it ends, maybe a "continue" screen before the powerups show, or a confirmation button?
Fun game, easy to pick up but hard to master, great work!
Cheers :D
