Got past the spider boss! I expected something else but there was just large empty room after another lol. I would try making the transitions between the 2 worlds less jarring next time.
Seems like the engine might've been slowing you down too. I believe there are free visual coding tools for unity that should speed things up.

I saw the screenshots and expected a really cute little game where I wandered around doing mousey things. I booted up the game and didn't half have a heart attack when I entered the field, let alone when I returned to the creature in the witchy hat.

I wasn't sure of the controls, it seems WASD and left/right click? I appear to be able to switch between worlds by pressing E - not sure if that was intentional as I cheated a bit when I was running low on health.

What you managed to create is absolutely fantastic. I didn't expect it at all. The music is spot on too. Fantastic job guys!

Aahaha, the transition startled me at first! I was not prepared for for the witch suddenly popping up after talking to the character. Was super pleased with that though~ Cool idea with the mood/music/theme switch!!
