it starts soft... but near level 20 and on it turns into a frenzy clicking in the dark [in the blank, in this case (haha... terrible joke, sorry)].
my mouse was complining about the clicking, stopped at level 26.
overall: gets boring as levels increase and the random clicking takes place.
2/5
good game. the colors are somehow raw [and psychedelic in some levels], but no problems with that.
sometimes I can't see where the cursor is [e.g. in the "first race"].
good ideas for the levels.
4/5
