Thanks for the feedback and for playing! Glad you liked the style and vibe. You're totally right about the visual indicators. Due to the jam's time limit, I won't be able to fix the health bar or add more effects right now. Just a little hint for the second fight: the boss is meant to be a bit of a puzzle itself. It can only be damaged by water, and only while its mouth is wide open! But I completely agree that it can be confusing without proper visual feedback! I will definitely fix this and add better indicators in the post-jam version. Thanks again!
