As far as I can tell, this game started out as a set of programs called DSTAR for the TI graphical calculators by Joe Wingbermuehle and Andrew Von Dollen (there is also a version for the HP calculators - I'm not sure which came first...)
Since then, there have been several other versions. Last month, Stefano Bodrato made a version for the Jupiter Ace computer, and I saw a video of that version on youtube. This was the first time I had seen the game.
Since the game is based on 16 by 9 grid and has few moving objects, it seemed like a good fit for a quick Intellivision conversion. So, I made a copy of "Tag Along Todd" and started hacking away at it to turn it into DSTAR. Unfortunately, I kept adding features to the program, so it took much longer than I had hoped. But now I've about run out of GRAM, so I guess it must be done.

I would appreciate any feedback anyone has. I would especially like to know if it runs on a real Intellivision, since I have no way of testing that at this time.
If you press 9 on the keypad while playing the game, you can switch to an editor. You can edit your own level and test it out. Unfortunately there is no way to save your level. But, if you make a cool level and send me a screenshot (or a dump of scratchram), and (if I like the level and have the space,) I can add it into the game...
Currently, there are 25 "classic" levels (from the ti-83 calculator version) and 11 new levels that I have made.
I recently discovered that Atariage has a 2600 version of this game called "Astar", so I am calling my version "Istar". (Hopefully Apple hasn't reserved that name for something...)
Thanks for checking it out...
