Did normal maps by hand, if you're interested check out the devlog ;) It's on the game's page. Took some work, but I honestly think it's worth it for the extra depth, especially considering I had to do everything out of primitive shapes due to my lack of knowledge on any free 3d modelling software and my old 3dsMax license no longer being valid >.> Hope that answers the question! And thanks for the compliment on the game :D
