[RMXP] PLATFORMERS?

I read about that new game contest and I might actually try to make a Halloween themed game in time. In fact I already started. At first I was actually trying to make a sorta top down platformer with RMXP but ultimately changed my mind and have moved to another idea. There is a jump command in the set move route options but I dont think it works well enough especially when the character is in motion. That said has anyone attempt a platformer with XP before? And if not how do you think would be the best way to attempt platforming with XP?

Thanks Marrend :D
