Gem Eater
Gem Eater is a mobile puzzle game where you control a snake that lives underground and has to eat gems. You score points based on the gem color, the more you eat the same color, the more it becomes worth. Strategically deciding which gem to eat next is key to victory. The more you eat, the more impassible clocks will fall down that will eventually trap you, unless you can clear the stage. Stages are cleared by reaching a target score within the allotted time, and without getting trapped.
