Hi chsxf,
it turned out, that Arlasoft was not the only Atari 2600 developer who liked your game very much. I have added some of my own ideas to it, therefore I call it "Top&Tom 2". You can find my version here.
We now plan to release the game on cart in the AtariAge store. Would that be OK for you? If you want to continue to communicate in private, please let me know via AtariAge. My Username is "Thomas Jentzsch".

Thanks for the heads up. I have obviously no problem with derivative works based on Top&Tom. However, just to let you know, my company and I will launch the game on mobile very soon and there may be an issue with the “Top&Tom 2” name in itself. I haven’t tested your game but I’m sure it is perfectly fine. I would only require a change of name I guess. Do you think it would possible on your side?
