Thank you for playing and the feedback! Yah, I made them super tanky (especially as the waves progress (up to a 4x modifier IIRC)) since there is no ammo limitation and we needed the player to die... so they get more aggressive and tanky. It was definitely not playtested as those changes landed minutes before the submission deadline. Also agree on the hit feedback, it's a fundamental missing feature and there is a few of those.
