Thanks for warm words. As for the scope of the game, it was doable because I based it on my own engine which I've been working on for over a year. I heard many things recently about difficulties in creating roguelikes in Unity and it encourages me to reveal my engine and make it open-source.
Thank you for precise bug report, I'll look into it.
And yes, I'm Deaven from old adom.phx.pl :D A ty kto?
