A lil' Crimson Red and A lil' Brushed Metal and this came out just in time for the Crimson DS! ... The camera can't really pick the tiny pixel detail, It will look nice on the DS. Hope you like it!
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
