Game's looking cool. I enjoyed ZQ1, and I like this one too - let's wait for Part 2 then. :)
By the way, thank you very much for the "normal" .tap and .tzx files on this one! Now that you got that sorted, do you think it might be possible to convert your previous games to the same format ?
Besides being more compatible with different emulators, it's better for storing due to the much smaller size (and I'm pretty sure by the time you games get added to external TOSEC/MAME collections and the like, someone else would convert them anyway, so it's better to have them in the proper format from the source/author than relying on third-parties altering the original files).
Thanks for considering, cheers!
