Hello! I have used your sprites in my first game non commercial game: The Mysterious Dungeon. The sprite I used was the blue knight.
The game can be found here: https://rpgenerous-studio.itch.io/the-mysterious-dungeon And here: https://gx.games/games/kbhk18/the-mysterious-dungeon
I would like to thank you for your work, and I will donate/support as soon as I can!!
