* The MP bar. I died too many times waiting for it to re-load before I could heal.
* DEMYX AND HIS FORMS. That took me FAR TOO LONG.
* The STUPID cycle thing in Space Paranoids. Ugh.
* That one boss in Port Royal that required you to recover all the coins... over... and over... and OVER.
I loved pretty much everything else about this game, though.
