After what seemed like ages, I finally found another boss – a giant ram’s head thing that threw ghost faces and stuff at me. He was really easy to kill though, as I had my magic fireballs-that-spin-round-me on (which killed most of the projectiles before they hit me), leaving me to just jump-whip his head over and over.
Once dead, I could hit a switch which I think has now made new pathways available elsewhere on the map. No new move power-up yet though, which is what I was expecting. Bumped into Hugh Baldwin again too, who seems to hate me. Hurrah!
I’m now exploring some area where there are lots of poisonous moths and some triffids and things.
