You somehow managed to strip down the autobattler mechanics to a simple, yet super engaging and fun experience, which is super impressive, especially for a jam! Hopefully you’ll keep working on the game after the jam, as with some minor improvements and polishing, it could be something great. As for feedback—I disagree with what others said about balancing. At first, I wouldn’t care too much about tweaking the numbers, as I believe that it’s better to gather A LOT of feedback before doing so. Focusing on the gameplay mechanics, UI and replayability elements (such as meta-progression, a high score page or leaderboards) would be more productive for this sort of game at the early stages of design and development. Congrats!
