Nice fun entry! I like the music choice and the visuals is also fairly nice. I didn't get the weird sound effects you get when the ball goes into the hole, but that's not too bad. The resolution on the web build on both windowed and full screen is not correct, but the game is still playable.
The mechanics is also fairly simple but fun and I enjoyed it.
One bug I have found is that the first time I load the final level, there were invisible hitboxes on some of the empty tiles, preventing me from completing the puzzles, even after I had figured out the solution in my head. I thought I was not supposed to go there so I tried some random things until I died. Then when it reset the level, there were no more invisible hitboxes so I could completed the puzzle.
