Hello again! Thank you for the kind words! ^^
For the inventory slots having different colors, it was just to be able to separate them as different drawers, so no it doesn't have any meanings behind it. It's true that the number of available seeds went completely overboard, considering the numbers of slots available and the ability for someone to search for specific ones X) We will definitely see about enhancing the inventory design to make it more easy to go through.
Thanks again!
