Eggbert

Eggbert is a simple side scrolling game in which you must collect all the treasure in each level, then find the exit to proceed to the next level. The controls are very easy- Up arrow to jump, and the left and right arrows to move left and right. Also you can use the space bar to use items in the world such as helicopters and drills. There is a quick 4-level tutorial to help you understand the basics.

There's also a level editor! It's not that hard to understand, but there's a help window if there's anything you're not sure about. If this doesn't help, feel free to PM me your questions or ask them on the forum! So tinker around with the editor a little bit, it's great. :) There's now also, FINALLY, a simple way of sharing your levels with others. Give it a go!
