Well, the answer is simple: make every level two parts. So have a Blocky World Part 1 and 2, and so on. So basically the levels will be in two parts like in Sonic games. This will allow me to create more levels without having to program more tile and enemy code. I figure that I spent all this time programming the level components, I might as well use them some more.
It shouldn't take too long to make the levels, considering all I need to do is load up the level editor and design them. Since I have Spring Break next week, it seems the ideal time to get this sort of thing done. I won't be releasing a demo after making them, so you all will have to wait for the final release to play them.
Although I reluctantly go back into the world of level design, I feel it will be worth it in the end.
