how about a special room called 'freez' ! its like tag but when sham touches you, you freeze and dissapear... the last mouse standing gets to be sham next round (the sham is the one that freezes mice) + if u... well, if you... think the same...
here's my idea, I think we should have sticky blocks, so when u touch them you can stick and then move to get off, I think it would be useful for WALL JUMPING,that would be fun
[+] if you agree ;)
