Memerize,

to get a score about 4000 it takes some fast clicking and mouse control.

As for the feedback, "thanks much".
1. I've always wanted to do the enter key thing. Just never got around to figuring it out.
2. I always forget those. Perhaps ill also include your ranking (spot number).
3. I'd rather the users go to the page instead. Makes it so if people (no idea why they would) put the game on their website it would go to my website instead of the rippers.
