Simple fun game, but with a few thoughtful touches like the Next Level indicator, and random ball color changes (I stayed on longer than i should to see how many colors were possible, before i realized it could be randomly picked haha).
I like the retro music and sfx on leveling up.
Minor suggestions would be to hide the mouse cursor on game start. Feels kinda distracting over the Pin. Also, i wonder if giving a range of velocity in the higher stages will make the game feel more dynamic.
But overall, a fun minigame that i enjoyed!
