Thanks for the review. Slay the Spire was extremely influential to me so it means a lot when people compare us to that game.
Regarding your notes: Yes that was intended. It is precisely to prevent people from simply shrinking down a particular part without a lot of thought. Though the execution should've been better, as it'd require pixel perfect mouse detection. The obvious limitation to that was the time constraint of the Jam.
Regarding the torso - I did try to design the body parts such that the most optimal strategy is not always going for the torso right away. A destroyed bodypart will not only reduce the torso's health by 20% of its max hp, but will reduce the overall attack of the enemy. I think in the early stages in the game, it's vital to keep your own health high so that you can get some of the attributes rolling. The game's balance is completely off though, there are cases where player can achieve infinite floors as they scale faster than enemies. So this is definitely a "solved game" (though very much unintended) with an optimal strat, but I don't think "always attack torso" is it.
Thanks again for the feedback and the opportunity to discuss game design in such an open arena :)
