-In the menu, you should be able to use the D-pad instead of the analogue stick. I accidentally hit a diagonal on the analogue stick and changed the language unwittingly.
-Did not like how I couldn't move my character at all while using the weapon. It made the character feel stiff and lacking in agility.
-The inconsistent sprites and text broke immersion. The numbers in particular felt like a placeholder.
-Monsters took a really long time to die, and I was usually just spamming the same button. There's almost no attack variety, like different types of swings you can chain together. It felt like a grind.
-The monster sprites honestly did not look good. It was hard to tell what anything was, and they didn't look very cool or memorable. The artist should focus on design fundamentals, looking at other successful monster sprites for inspiration.
-Lack of agility and variations on the main attack are in the most need of improving. Those above all made it not as fun as it could be.
