Firstly, thank you for playing my game! It's nice to see my jam game still getting played months after its creation!
Thank you for your bug reports and suggestions, the lighting definitely needs work, and I learned a lot about collisions and clipping making this game as it was my first time working in 3D. I like the idea of adding enemy farmers to make the game more interesting! I plan to revamp all my jam games this summer so I will definitely take your observations into account.
Have a great day!
