I truly appraciate your feedback and I'm happy you enjoyed the game! About the download thing, I know it was not the best choice, I'm really sorry about that. We still have to learn a lot about optimization and maybe the next time we will be able to upload on itch.io. Btw do you happen to know any better alternatives to google drive?
When I saw the material stuff, it was crazy for me too ahah. I definitely have to ask my friend, because if I don't get wrong he did almost all the materials itself. He would like to become a tech artist, so he's studying shaders and how they work and then experimenting.
