Crystal Wave is a score-based arena shooter plays like a combination of Defem and Jan Willem Nijman's Coptra. The objective here is to collect as many green gems as you can to maximize your score, and at the end of each game your total points haul can be submitted to an online leaderboard for fame and recognition.

The controls are limited to the WASD keys for movement and left mouse button to shoot, although you can also right-click when the bomb gauge is full to destroy everything on screen while attracting all gems towards your ship. Small gems reward players with just one point, while large ones bestow a full ten. (Windows, 4.19MB)
