Hi, thanks for your interest in adding this to your library. I've actually been considering updating it with support for all types of gamepads and other various, common game-related symbols.
Anyways, problem is, at a glance I can't see any specific licenses that fits the donationware + uncredited + commercial use + don't resell as is model. CC0/Public Domain kind of fits but not quite due to the latter parts and I'm not sure what alternative would satisfy Germany.
If anyone is desperate for a super low-res font that is damn near unreadable, I made this 3x3 spritefont for a lowrezjam a couple years back that might be of use if you modify the colors.
