Firstly, thanks for trying it out! Secondly, I’m sorry that you’re struggling with the timing of the boss :(
I’m very interested in doing everything I can to make this game feel fair, so thanks for informing me! Once the judges have finished judging the jam entries, I can upload an update that fixes balance issues.
Just so I can address the correct issue, is the issue with timing because when you attack, the boss recovers from the attack too quickly, while you’re still inside the boss’s hit box, causing you to take damage?
In the meantime, before I’m allowed post an update, if I can suggest you give it another shot with this tip in mind: I find the first boss a lot easier if I chase her to the left side of the arena and use that platform to attack her quickly and duck under it when needed. Hope you’re willing to give it another go :)
