Most of the instructions are inside on the small white box with an i. The survival mode all you do is survive and for bossfight (Newly added), survive against a boss. Classic is a normal set of levels. (IF THE BOSSFIGHT KICKS YOU OUT, THEN EITHER YOU DIED OR BEAT IT.)
98% work goes to @SproutMr-P. Classic, Survival, meteors (Level 125/150), and warnings for meteor art goes to %2 @ICODEONSCRATCH2
