Thank you for your suggestions and feedback! Could absolutely lean into the light and dark tinting of the enemies. With some more time we probably could add variety of enemies that could help distinguish their affinity a bit more clearly!
Sure! In fact it was not clear at first, I only understood the resistances after reading the description, so definitely a tutorial could help, but yeah I think visuals are better (show don't tell). maybe with damage labels showing damage done and critical/effectiveness of a different color
We discussed a tutorial, but since it was a game jam we didn't actually budget enough time for an in-game tutorial. If we continue to develop this project, that's something we definitely would consider.
