I believe I understand the visual bug you're referring to. I noticed it when I attempted to run the game on a mobile device; I assumed it was only affecting mobile. Thanks for the feedback!!
The game appears quite easy initially, but from level 6 onwards, the enemies become faster and unpredictable. It's fun, though I only reached level 8. The mouse controls are excellent, and the gameplay is simple.
Waiting for the coins to bounce vertically for a smooth catch, but some of the red ones spawned directly into the hole. Overall, nice gameplay and controls.
