In-game. -TIPS- ~You go down faster than you go left, right and up, so don't hold the down arrow or S for too long. ~Staying near the bottom gives you more time to react to the fireballs, but you slightly go down every 0.1 seconds, so pelt a bit in-between so you don't hit the ground. If you want a challenge, stay in the top half of the screen.

Will add costimizing... eventually and if I get lots more entries in my contest that *sniff, sniff* has only *sniff* one entry, which is *sniff* not even enough to fulfill the prizes. *sobs* Please view my other projects, and join the Creature contest, which are both accessible by clicking the grey bar near the bottom of your computer screen.
