I've also got this following version: v1.02 (or v1e): https://web.archive.org/web/20130127032852oe_/http://www.handdrawngames.com/DesktopTD/DesktopTD1e.swf

I don't think someone has posted about v1.02 before? Also, in case anyone else runs into the same problems as me running v1.21b with the Adobe content projector, it'll crash if you launch it with the debugger.

Also the website at https://web.archive.org/web/20130119105322oe_/http://handdrawngames.com/DesktopTD/Game3.asp has keyboard shortcuts, tips and leaderboards that some people may find interesting.

The archived website also has v1.5 and v1.21b but they're the same files as posted above.

I'm happy to help out if you like
