Really fun arcade game! The controls felt responsive, and I liked how the difficulty gradually ramps up—it kept me wanting to beat my high score.
One small suggestion: adding a stronger sound or screen effect when hitting obstacles or collecting points would make the game feel even more satisfying.
And the game takes a little while to load, so I'd recommend testing the loading performance if possible. I think a faster startup would make the experience even better.
Great job overall, especially as a browser game!
