Thanks for playing and the feedback.
We are working to optimize the tutorial. There is a lot to cover, but also want it to flow better. We plan to try some alternatives such as popups showing different info, and adding a help screen accessible later for a refresher. We will also add an in-game skip in addition to the setting to skip it. The affinities are a big pain point for conveying important info, but also something that isn't as important early on. That mini-boss fight with the knight is the first fight where they can really shine. We may add something later on, but before that fight, about them as a reminder to equip the Slimes with the things that match their affinities to be better prepared for it.
