Make it so you can have the backup char in the battlefield aswell, and you can put him/her back out of the battlefield at any time (doesn't take a turn)
First of all, the handling is -1 meaning you can't tilt at will (most of the time), then second of all, the game needs health, not just instantly, third of all, change the areas where you take damage, fourth of all, needs checkpoints, fifth of all, it needs upgrades, sixth of all, more textures and seventh of all, it needs level select (if it already has one, my bad)
