If the server has a problem and you "die" trying to teleport to the nexus you should still be able to retrieve your character, not have him dead because the game wasn't responding to 2 seconds of you clicking *nexus*
This game was waaay too easy. I think that you could make this game harder by adding different levels and have the planes shoot at you and get faster through the levels. Also, I think that you should let the plane move forward and back and have there be upgrades after every level so it will keep people enticed with the game for a while.
