I'd love to port it to switch one of these days. I made the game in unity so would probably go through nintendo's developer program for unity.
Yeah that's not a bad idea. The king unit can also keep summoning allies to battle assuming they have enough mana. Probably a good idea to put a cap on it. I think if I were to add a cat unit I might move those skills under a summoner unit class. Or random summoning might be interesting.
Thanks for the feedback :)
