load time!

I have a game, called mario (bros ) alpha, and the load time of the game ( 1 min.) takes longer than diamandsion assault! But it not a very big game, so i was wondering: what ar the things that the load time make going so slow?

The longer the level, the longer the load. That’s why my levels are short in Diamondsion Assault.
I used to have long load times too.
