So what are you going to do then?? Have each screen be a different level? You can't backtrack and explore around then. But then I guess it's too early to decide exactly what it will do and how.
But here's my two cents: if you use a different card for every room you can set it up however you like and have each card say what rooms it connects to.
but theres alot more to it, you gotta save all the enemy postitions, enemy types, pickups, keycards, and so on for each room. not to mention it would make level designing much harder. i think the gameplay should be fast paced, and backtracking would just slow down the experience
basically right now, advanceing to the next level restores your regular speed so you can get the boots pickup for each level, keys get cleared, and health and ammo carry over
i want to alter the graphics more for the different enemy types, and ill work on a boss fight, if you fight boss' one on one we can probly add projectiles for the boss without slowing down the engine
