Tap on the ghasts and trees. Also, there is a time limit and Steve is the special one. When the timer get to 100.00, the game stop and then check your score. Also, if you want the game to be even more fun, then do a 2 player and see who gets the most points.
This is a Minecraft version of wack a mole. Fun fact, the tree gives you 0.1 score, ghasts gives you 1 point, and steve gives you 10 points. Also, don't tell anyone this but, there is a high chance that you can click Steve multiple times. One more thing, there are different sound affects in each tap for each characters.
