Hey there, loving the game so far; purchased it after watching Neco the Sergal's playthrough, got it on Steam!
Found a bug in the Ancient City, if you stand in this exact spot and keep looking, you can get an infinite supply of stones.

Oh nice found! I've been trying to get rid of those infinite item spots :D
No problem man, if I find any more I'll let you know!
