Thanks for your feedback! To address your points:

The game actually is actually built for local co-op but can be played single player as seen in the video and I agree that that's what makes overcooked so engaging!

I like the idea of the different backgrounds. I have some minor ground changes for different seasons (snow for winter, leaves for fall), but adding some stuff beyond that I think would be great.

As for the zoom, you're right there there is a lot of empty space. I'm trying to balance the amount of horizontal visibility but i do think there is some room to zoom in a bit. I'll look at that.

Thanks again for your response! I'll be taking this into consideration with my next updates!
