First click on the green flag and then the one on the screen.To play use the right and left arrows. Don't let the falling monsters touch the spikes! Also there is no timer but if you prefer timers I can add it, just comment it. There is a monster on the left you can use it if you are playing on something without a keyboard. If you click on one another appears this is fine so don't panic just click on the one wich appears.
If I get lot's of likes I will add more characters. So comment below how the new characters can look like.
