Not a bad game, though it does get a little repetitive so could do with a little variation over time (eg: more than one pixel to catch maybe?).
I also found the sound effects a tad irritating.
I agree with you noc7c9, there are a lot of possible improvment for this game ! I also thought of reducing the size of the pink's pixel. For the sound, i apologize, it's really not my best part .... ^^. Thanks for rating !
