Thank you so very much for all of these comments! Polimerikum was also a great experience (I believe it was updated since I last checked it, might be time to go back to it) and it's great to share between fellow indie devs.
You are right about the shadow bias...there's this shelf in the study/office room especially that just looks...ugh. :P And don't worry too much about me being hard on myself; as I commented elsewhere, it's mostly a question of gaining some distance after release to reconcile with the game itself. I like it a little better now.
I hope my next titles will keep you as interested as you were in this one. :)
