Levels looked cool but I was a little confused at times whether or not I was actually moving. Maybe like a subtle trail renderer, or a fading highlight trail on the squares you've been on might help with the sense of movement and direction.

I found the 2nd level really hard to see the end point and couldn't find it in Volcano. I'm not sure if it was that the levels were quite large, or I just kept going around in the same places!
