I'm glad I have convinced you to try Backbone, I've loved using this program on my Amiga ever since I found out about it myself. It's a shame it went so unnoticed back when it came out over ten years ago, as with more users and more support, the author probably wouldn't have abandoned it before adding all the extra features he planned. I wish someone could find him and ask if he'd like to release the source code, the Amiga community could turn it into the ultimate game maker, replacing all the Amos routines with optimised ASM ones or make it more system friendly.

If you would like to download some example games made in Backbone to try on your Amiga (or UAE) to give you an idea of its capabilities, get this pack - http://www.spin.net.au/~amiga/BackboneGames.lha and this quick demo of a Sonic type game - http://www.spin.net.au/~amiga/Sonic030.lha
