Tower Offense has been updated, just to round off some rough edges. You can download it from Mediafire.

Also, its code has been made public domain in form of a Mercurial repository. It is probably not the tidiest code ever, but if you are new to games development and/or XRhodes, you might find it helpful. (If you are also new to Mercurial, a great tutorial can be found here.)

To work your magic from the command line:

hg clone https://bitbucket.org/zyndor/tower-offense

Please note that actually building it will require XRhodes v0.86. Just a couple more days...
