Fire Fighter is one of many VT09 titles created by JungleTac. This game is an unofficial port of the NES game Flying Hero, and the sprites and levels were even copied from that game. The gameplay is largely identical, but includes some differences such as the firemen now moving slower.
You control the two firemen holding the trampoline at the bottom of the screen, moving them left and right to catch the Flying Hero and launch him back up to rescue more citizens and put out more fires on building.
