What you're asking is quite alot, but I'm sure some scripters are willing to make some of them. If there comes an easy one, I can maybe make one myself too. BTW, I see you're really basing your game off MS (MapleStory)

. I love that game myself too. GMS FTW!
I think Remexos's Character Customization Script is the same as 5 and it is released if Remexos gets canceled. I'm sure some scripter can make it. I'm not good enough for that atm...
That level up thing should be really easy. Uhm, should other players see it too, because then RMX-OS should send over the data of the level up sign, and I don't think
I can do that

. 9 is probably quite hard... And could you give more info about 8?
