Thanks for your feedback! 💙 The game was mostly done as a quick game jam experiment for us to test our grounds in beat-em-ups a few years ago, so unfortunately, when we look at it today, we have to admit it wasn't really the most balanced experience. 😅
It might take some effort, but our recommendation is to try to de-sync the time that Bluessom does her attack compared to you. Her 'area of effect' singing can happen even when before you use yours. Like your ability, she also needs to wait for her cool-down to happen before she can use it again. So when you see that she used her ability, but you still have your 'Ultimate Sax Drop' ability available, you should use that opportunity window to strike back as there will be a moment where she won't be able to convert her fans back.
Also remember that enemies get stunned momentarily when you hit them, so using certain attacks mixed in with each other might create a good rhythm where you can convert fans quickly into your side before they're able to retaliate back. You can actually combo attacks if the skills are available!
Let us know if you were able to defeat her!
Thanks again! Cheers! 🐳
