Solid entry. Quite a good example of a simple mechanic (clicking changing your shape fill) in a simple game (move your dot to other dots) which leads to quite enjoyable gameplay.
Sounds always help, as would a title screen (instead of the game immediately starting on load) but didnt detract from it too much. I did get some slowdown/jittering from the second wave onwards - unsure if this is on the game end or not (solid gaming computer so surprising)
Nice one eh.
