What annoys me about "developer interview" is that he's not the developer! The developer is John Jones-Steele (who ported Sim City 2000 and Ultima VI to the Amiga, and Speedball II to the CD32, among many other things).
If you want to ask any pertinent questions to the actual developer let me know and I'll ask him next time I go next door....
FWIW, John would I'm sure have no problems with an Amiga port of Putty Squad, but it won't be up to him, as he's just the coder.
You can see his company Facebook page here:
