Ultraviolet

Ultraviolet is an action game played on a grid board. The players (either two or four) are restricted to up and down movements on opposing sides of the board. Each player emits a straight light beam which is used to collect the gems which float around the board (by catching them and tapping a button to pull it). Collecting gems gives points and, more importantly, fill up the health meter which constantly drops over time. When both players battle for the same gem, a button mashing competition decides the winner. The goal is to outlive the opponent.

Besides gems of different sizes (and health worth), there are two special gems: bombs (can be used to clear the own half of the board) and anti-gravity gems (tilts the board towards the opponent). The latter are important because all gems which fall off the player's side have negative consequences on the health. Another important aspect is the combo meter which fills when the player collects gems without losing health: a higher combo means faster collection speed. Those points can also be used to crush gems which then emit movement energy on nearby gems. New gems only enter board when the whole current wave is gone.
