i like it but...
There is a MAJOR GLITCH. If you go fast enough, you can just blast through most of the skinnier walls. But l do like your way of stopping the regular mouse-click glitch. I also like ow you made it much harder by making the dot kinda float to your mouse instead of always being on top of it (Giggity!). So yeah, make all the levels without skinny walls, More color, and just basically make it smoother, and it would be great.
