Thank you so much for the review and for getting so far in the game! It's a shame that the grammar ends up being poor, english is not my primary language. I try to get better at it, but I sometimes end up using a translator. I'll try to revise the text and make all the adjustments I can.
The level design is also rough at times, and yeah, when you can't reach the rotating platforms, you have to leave and re-enter the room, which isn't ideal. I'll have to fix that, maybe by adding a lever on the floor to reset their position.
You can actually break arrows by attacking them, but it's fine if you missed it. That particular chest is meant as a hint that you can break arrows, and as a small reward for figuring it out. It's not necessary to advance, so it's fine.
I'll also nerf the bosses, and yeah, definitely placing the last save before so many cutscenes was a bad idea, lmao. I also plan to add a fast-forward option to cutscenes to make losing feel less sluggish.
