I need help with loading bars

Everybody knows loading bars. But are they useful? Eh, sort of. Most people on flowlab just use them to add a little spice to their game, but they aren’t all that useful. In an attempt to make them useful, I added a loading bar to a game (after I put a lot of blocks in a level), so that the loading bar would show until the level has been loaded. I’m kind of stuck, though, and need someone’s help.
