Use the right, left, and up arrows to move the Pterodactyl. those arrr all the instructions. FYI: you gain points fast when touching the crystal because of how i coded it. comment your score in the comments.
this is probably the worst chase game you've ever seen, but it is a chase game, and it works. (kinda) its for tech ed, and it works. i'm not griffpatch, so don't expect anything suuuper good from me.
