Fun game, really liked the concepts and mechanics you used in it: the visual way you demonstrated the countdown until your death via the reduction of the size of the ball was really cool. I also really liked that each area did have some ways to use powerups from other areas. I think the game could benefit from some checkpoints, particularly because since you can't see the entire map at once sometimes you have to run in one direction and hope medkits are there. If there aren't any, you die and have to go back.
