Loved the game. The combat was fun, the level and enemy design was great, some of the bosses where extremely creative and fun, with some stuff you definetely dont see in newer games, and the music was fantastic as in the previous 2 games. The game was also really hard! Even towards the end, when you think the bosses are getting easy, the last boss bumps the difficulty back up again.
The bad stuff I found was just some jankiness that is the norm with pc ports of old jrpgs, weird controls, mouse not mapping correctly to full screen in game.
I dont know if I can't say this is a good thing, but compared to the previous 2 games, you don't need a guide for this game,

Looking for a challenge? This game is easy to pick up but tough to master—once you get the hang of it, it’s a ton of fun!

It doesn’t officially support gamepads, but Steam lets you map the controls yourself through the SHIFT+TAB menu. Plus, there are plenty of community-made configurations, so with just one click, you can play Ys with a controller like it was meant to be.
