Well just include something which can decide how any hearts everyone has, in fact try to put a NON hearts function(Can you try to make more hearts then 5?) Also a option if people can use carrots or not to get more hearts (if possible). And errr... a function to block laser shields and a Ban funtion, like when someone gets kicked and he comes back and he does something stupid again he gets banned or after 2 times kicking he gets banned. And something more if its possible:
A option which wont allows cheat programs like: Gamehack, Ultrawarp 1/2, Megawarp, TSF warp etc. I know you will say:"but the program wont able to kick people which use programs which are released AFTER the program script was done with the current cheat programs", but isnt it possible to add a Update on the program so when a new Cheat Program is released You automaticly let the program Update it. Hmm that sounds a bit diccicult. And uhm...also at the cheaters list put the IP's of them of the cheaters. Another option: Dont let ppl allow to come in your server which used a program like Jazztool or Xjj2to go in, without filling in the pass. And eh a option for No Cloning. Well this sounds all so difficult... I hope ya can give it a try.
