Dextram

This arcade shoot 'em up has no shooting and you can only turn right. Avoid waves of enemies and get points as they crash into each other. Pick up power-ups, such as a large laser or a force field to destroy the enemies. Die, get a score and repeat to get a higher score the next run. Avoid and outsmart enemies by figuring out their moving patterns and make them crash into walls or each other. The game is controlled with a single button because you move forward with no option to brake and you can only turn right. Pick up power-ups to make it easier to destroy enemies. Kill enough enemies with a power-up to trigger a combo and be rewarded with an additional power-up.
