[quote="nepO":93d1vy1b]we might end up doing tiles anyways but thats not gonna look as nice.
There's absolutely no reason why it couldn't look exactly as it does now by using tiles.
Think of it logically.
Every piece of graphic you have in your large bitmap can be cut into small pieces, eliminating all the blank space in between.
You can then stitch together the scene using the smaller pieces, getting just as much variation, but using a lot less resources.
It just comes down to planning.
If this is indeed for a school project, then you're going to get marked down severely for ignoring one of the more important aspects of game design.
