My next goal for the game is to make it so that the player can actually progress to the next level. Right now I have to go into the code and manually change it every time I want to change the level.

With Blocky Man, the method I used to do this was very simple. I named the map files:

level1.txt
level2.txt
level3.txt
etc...(not exactly, but something like that)

Than I hacked the code to make the levels play in order.

Now I'm going to code it so a group of levels will be packaged into a "world". This will allow people who make their own maps to group their levels. After all, I'm hoping to make this game something people will want to create maps for.
