I love this set!
I’d be willing to make a pack that is tailored to tiled. I am thinking terrain brushes (so it will automatically pick the right tile for drawing terrain) and pre-made sprite animations (so you can just drop them into the level editor.) The great thing about Tiled is that it works for many different engines/languages, so it’s a nice general open-source thing to layout levels in.
I’d also be willing to make a little demo-game for one of the engines I work on (node-raylib or raylib, in C.)
Let me know if you’re interested.
