You're playing it wrong: Final Fantasy VI

From thecrankyhermit

Don't play the mobile/Steam version. Just don't. I won't even honor its atrocious spritework with comparison screenshots. It makes Gau cry.

You can't go wrong with the SNES original (called Final Fantasy III), which is emulatable and available on Virtual Console. Alternately, the GBA port "Final Fantasy VI Advance" has an improved translation, more content, but worse music.
