I’m probably not going to open source the project, but the original game that was made in Unity was open source, and a lot of the logic for growing and harvesting crops is similar. The movement logic is also almost the exact same, the only differences with the remake is that walking around has better animations and also faster.
Here’s a link to the original game’s Ludum Dare 52 submission page, the source code should be linked there: https://ldjam.com/events/ludum-dare/52/down-to-earth
Thank you playing the game :D
