Thanks for the thoughtful feedback! Yeah I tried to add some text to the 'How To Play' screen to explain how it all works, but honestly I wrote a lot of that at like 4am last night so it's probably not as coherent as it needs to be lol. I think ideally I would have liked to put some feedback in-game as well, such as showing on the cards explicitly what your bonuses are.
As for the AI, that definitely became a challenge. I originally wrote AI behavior to basically just pick enemies and moves at random (with a slight preference towards attacking) with the intention to update it, but never got a chance too in the time limit. I think this definitely leads to some weird behavior. The puzzle approach is a great solution, and definitely one I'll consider for future jams.
Appreciate you playing and all the insights you had!
