Really well done. I have enjoyed my first play of this quite a lot. I ran out of continues but I will definitely be coming back for another go.
One thing though, I got caught in a death loop. I fell into a water pit to the left of the entrance door in the tower. It spawned me one tile to the left of the platform and up a bit. Then I just couldnt get back on to the platform when I was holding right. Just kept falling in the pit until i ran out of continues.
Should be an easy fix. Again, well done. It's a really fun game so far.
