Very simple game, good fun.
To keep the game going on forever:
Hit the bad guys (adds a little timing)
Get the + timer (add significant timing to extend
your game play for another few mins already)
3. Avoid hitting the good guys
getting the - timer
repeatedly, if you want to continue hitting
another hour or getting 100,000 score is possible
provided you are patient and your hand can take
neat game !
If you click and hit nothing you lose time.
I can go on the next 1 hour playing this
This game will never end. (if you
play properly of course)
