Ponger by tomputergames is an enhanced Pong made for PICO-8.
In this game, you need to try and get the highest score without getting burned. The trouble is, the further you pull ahead, the more fireballs appear on the board. Bounce back the fireballs by blocking them from your side. Every time you bounce a fireball, it gets hotter and faster. The more ahead your score, the more fireballs will be in play. Every time you let a fireball in, you lose a life. You can choose between playing with the computer to keep the scores close and slowly increasing, or take a risk and pull ahead for the chance of scoring with multiple balls at a time.
