Cool little game. I do have a few remarks though… the reset via left mouse button doesn’t work properly. When the game restarts, it triggers the lose animation and you immediately lose again. The initial speed feels a bit too high for my taste; a smoother progression would have worked better here.
The animations and presentation, on the other hand, are very well done and appealing! These are just small tweaks, but they could improve the gameplay quite a lot. Good work—keep it up.
