I love this! suddenly making me feel/realize I over-thought things!
Great Idea and I'll be sure to add it. (once the Jam is over)
One slight detail though, is it that the dots themselves are too small, or that you need to be too close to the dot to register?
One unfortunate thing that happened with the game is screen resolution affects the game resolution. Higher resolution screen may get smaller dots and that might feel harder too (it has its own pros too).
