So I was looking through my old favorites...
And I found this. It's hard to say how easy or hard it is, since sometimes dots will be in nearly impossible places on level 1 and sometimes they'll all go right down the middle on level 10. Eventually, and suddenly, the game becomes pretty much impossible. I'd suggest preset dot patterns, variety (Walls, reversed controls, levels that are almost entirely red dots... you get it. OOOOO That gave me an idea for a level that starts out as a forced, twisted red tunnel of dots, then at some point a blue dot appears on the outside of the tunnel and an exit appears in the side of the red tunnel when it's about halfway down the screen. Then you have to get back in and do it a few more times. I should make games...), music, some sort of final level, and maybe a bonus life every 50 points or something. I hope you improve this game, because with those kinds of things it would be my absolute favorite dot avoider.
