How do I create multiple levels?

i want to create many many many levels example:100 levels so the game would be good,but the only problem that I don't want to recreate the level on each layout,what to do if I just want to increase the speed of the enemy without adding all the other events?

Is there a way to duplicate an event sheet?

If there is no way,then how do I copy the conditions?

Please help if you can help in any way.

It's generally wise to have an event sheet with the bulk of your game logic which you then include in the event sheets for your individual layouts. See the manual entry on Event Sheet Includes.

Thanks, I will try your link.
