Thanks. I like to think I'm fairly competent on the artwork side of things by this point, but I am learning about everything else as I go. Multiple people suggested including some purpose for the interactability in the town and I agree. I'm working on that.
Getting the difficulty curve right is a bit of a challenge as not everyone will see it the same. Further puzzles get quite a bit more difficult, so I don't want to make the first ones much harder, not yet at least. The puzzles with the rectangular parts are my least favorite as well, they didn't end up working how I thought they would. I have been messing around with them, but I might end up changing them entirely, not sure yet.
Anyway, thanks for the feedback.
