The room with the eyeball high up and it alternates shooting out eyeballs that are electric or fire/explosion. I feel like I tried everything and you can't leave the room. The eyeball is too high to reach. Any help?

The keyboard buttons aren't supported. I went to the controls settings, i changed the buttons to those of the keyboard and when i try to play the game nothing works. Then i go back to the controls settings and i see that the changes haven't been saved.

It's too bad I couldn't get the other heart before the Stabako boss, after I had died on the boss, the area was blocked off. I had gotten it before but because of how the checkpoints work if you enter the area, it saves what you have at that point. So even though I had 9 when fought the boss the first time, after I had died it reverted back to 8....
