1)I too am having problems with connecting
2)how about buildable "Mines" where if a player is on one it slowly increases ore,
this can also be locked(takes longer to unlock).
3)new gameplay modes:
i)free for all death match
ii)zombies
iii)team bomb
4)more maps/map editor(i can make maps if needed)
5)choice of player limit in rooms(14 is sometimes too many)
