BitRush is a small game made in FreeBASIC. I was inspired to make a game where slower enemies could catch you after being frustrated with horse archery in Mount&Blade, although there are no horses in this game (only circles :P)
In this game you collect as many rings as you can and bank them by escaping the circle, you lose your rings if you are caught by the bitts (enemies), which are coloured according to their propensities.
