First of all, great job! As others have mentioned, the voice acting is excellent, and the sound works really well. The musics fit perfectly.
In terms of gameplay, I find it a bit repetitive for my taste, but I'm not sure what alternative features could have been used.
It seems like you might have an issue with back-face culling on the hay bales. If you created them in Blender, there's an option to fix it called "Recalculate outside".
Nice Entry!
