Shield powerup:
—————
After beating the bosses on stages 1-3, continue shooting at the
eyes to reveal hidden shield powerups! Each eye contains such a
powerup. Remember that the boss can’t kill you after it has been
defeated, so don’t be afraid of it!
Cave Story cameo:
—————–
In Stage 4, when there’s a dotted line made out of land blocks, fly
over the rightmost block to reveal a pair of glasses. Shoot at them
to reveal Jack from Cave Story.
