I like the setting and the story a lot, a magician in a magic-free world. I probably missed something but is there any actual use to the mana potions and the food? The protag said his Mana was going down but in the menu it looked like it was full. I still used it but I was unsure if they changed anything. I'm usually not a fan of sudden deaths by exploration, but you did warn us to save often so it wasn't nearly as much of a hassle as it could've been. Unfortunately I got stuck at the statue in the snow biome as well.
EDIT: I've watched the google drive video of the ending and now I'm sad it didn't work in the final version. Really cool game, would love to see more!
