Hello Archerry,
First of i'd like to thank you for purchasing the game and playing it through till the end! This review means the world to me and you absolutely nailed it with the comment about what the game is in nature "Figure out the mechanics to then refine your own actions". This is the premise i wish to follow for not only this boss fight, but also any future boss fights I will develop for this game. My intended gameplay up until the next bosses is more of a relaxed, grindy, feel good hack n slash. Where as the bosses are there to truely test your skill, hone your mechanics and in the future optimize your builds. I hope that will suit your taste as well!
I will do my very best to address as many of the issues possible that you've mentioned in the comming patches and I hope to see you back again then!
As always if you ever encounter anything else, feel free to let me know and i will get to it as fast as possible 👍.
