Hey thanks! We really appreciate that. That was our first game together, so yeah sorry about the invisible walls. We really want to finish the next installment, so hearing that you liked it is pretty motivating.
No worries at all. :) If anything it shows you had the foresight to know I (and others) would inevitably try to go wandering off to the end of the world for some reason instead of towards your fascinating structure! :P
I'm glad you're motivated, because I can't wait to see what the next experience is like!
