Oh noooo. I think I just designed that boss badly, haha. I can tell you if you just focus on spamming damage on her you'll probably win the race! I believe in you!
I've considered patching the game with a bunch of rebalancing/remaking the game in a modern engine so it's easier to design. However, I've been so busy with other games I haven't thought about this much recently.
Thank you so much for playing!
