Tails ...and the quest for 100 rings

Tails ...and the quest for 100 rings is a Sonic fangame. The player controls Tails in a submarine and moves through single-screen levels shown from a side perspective. Tails has to collect all rings without touching the enemies which move around on pre-defined paths. Enemy contact subtracts from Tails' health bar (represented by a number) and the game is over when it hits zero. A level is won when all rings were collected.
