Thanks for playing and for the kind feedback! Some elements in the game are definitely a bit unclear, and I want to update it post jam to better indicate which enemies are doing their turn. The spider's sorta gimmick was supposed to be that you have to rely more on defending and healing to survive since it doesn't have a defensive spin, but that wasn't very well explained. Also the third boss ended up being a bit too hard (I buffed him on the last day, so that's on me), but to try and explain it a bit. His little minion guys heal him on their turn, but breaking the chandelier on them sets them on fire, disabling them for a turn, so that you can hurt the oilmancer. There's also only a defensive spin for his regular attack, not for the fireball attack (which triggers every 4 turns). Thanks again for taking the time to give such thorough feedback!
