nostr:npub1gmf3676tpvne7c3fhqtus6fg7tjpm749wzf5psjk4mu82lvnrxkszhfql5 I would suggest Dragonruby as well.  The engine is 2d focused and not free, but the developers offer "poor man requestable" versions and are just a bunch of really cool people. The engine handles the whole window making, delta time thing, and can export or update the game super fast, plus live editing of code. It's a bit unique but we've swapped all our 2d stuff there since it iterates FAST, which saves a stupidly good amount of time.
