Hi there,
If I were to use these graphics, I would use them in Comic Life 3 to create short role-playing games and comics for my ESL students. As someone who loves XCOM: TFTD, I think these graphics would be perfect for anything in that vein. I have noticed that there is almost no alien-esque graphics on itch.io, but there are quite a few shooter side scrolling graphics available. I was hoping to find something specifically for "aliens" and UFOs, like "The Abyss" or some kind of sea monster theme with an aliens twist. Although I have all of the Time Fantasy and Horror City series, they don't quite have what I'm looking for, I feel that the fantasy / zombie genre has been overdone in sprites, and there isn't enough of the Subnautica/Seaquest theme out there. I would like to see more of that, and these graphics could help me create the kind of content I have in mind. The underwater mecha/small fighter/shuttle subs would be a great addition and original. Also some big muscly marines and naval officers.
Thanks for asking.
If you haven't played through Terror From The Deep, I can't recommend it enough, especially for this theme.
