What a charming game! You art is great, as always!
I think the game is on the easier side, I pretty much one shot it. The end boss is really easy due to some not so great choices on the attack patterns, but it was hella fun!
Yes this was my first attempt at a boss fight, and a roguelike overall, the boss fight did take me a lot of head bashes to make lol, I did as much as I could in the limit, really happy you enjoyed :)
