Oh dear. If you play these games... you might actually want to kill yourself.

LIGHTFLASH

Click 'stop' when the light on the far-right turns red to advance. On later levels the order the lights flash in may change from just left to right. Yes, there is only sound on the first level and game over screen.

LIGHTFLASH 2

Same idea as the first game, but this time hit stop when the yellow light flashes. Green ones give you extra lives, except on the final level, where for some reason green and yellow swap roles. Do not finish the final level unless you want a headache. You'll see what I mean.
