Click the targets popping up on your screen to make them disappear.
You only have one shot: you win, you lose.
Every 10 waves you'll have to face all the targets you've missed.
Out of time? You've lost.
KNOWN ISSUES / ACCIDENTS
- Amount of targets missed has nothing to do with win/loss state. Not hitting every target on every 10th wave doesn't result in loss.
- Hitting 'W' in-game gives you a way to set the current wave.
I'll get to making a HTML5 version where you can disable these mistakes.
(of course this won't be the way the game was finished during the 48h period)
