Hi Robert,
Thank you for creating these wonderful assets! I've purchased many many of your creations and used them in a little game I've developed, as part of my ongoing efforts to learn programming. You can find it here https://2-tape-software.itch.io/in-a-flap
I've ensured you are credited in the game, which installs as a single EXE file (so the user cannot straightforwardly access any assets).
Hope that's ok and thanks again!
Cheers,
Steve
