Um...try buying the useful cheats at first such as the 3 star always option and the special move meter always full. This will help make harder difficulties easier, and nabbing you more points per playthrough. So save the fun stuff for later, oh and buy a character, they're stronger than the default 6 (sometimes like Ash and Shiva)
This will make the harder runs easier and well...nabbing you more points. Well this isn't really a tip it's just something that's helping me nab points
Teh Edit: So you get points deducted for cheats...oops

Edit: Ok don't want to save up for the expensive stuff (such as Rudra?)
Go to the store when blaze is sleeping (around early morning, 4 am, 5 am, etc.) Find an Item you want, and then steal it. You'll be locked out until you beat the game again and all points earned in that playtrough will go to Blaze, but you will have the item. So that's a tip for those that cost 90,000 and Up...but don't do it for the cheaper stuff
