yeah! ren'py is the only engine i feel like i understand, so it's more like this is the ONLY way i could possibly make a card game even though it's not intended for things like this at all haha.
ooh programming help would be super appreciated--this project is on hiatus right now but the next time i end up working on it i'll definitely reach out to you! another commenter asked to be able to drag-and-drop cards but i was struggling with getting that to function, so maybe that's something that needs the help of someone with more general coding knowledge heheh
