An interesting concept. Wack balance. Very slow.
I'm pretty sure I played another game last jam on this exact engine, numbers in the tiles included. And it seems that parts of that jam came back in the form of the lighting mechanic. This does raise the question wherever or not this game was fully coded in the jam time, but that's not what's important.
What's important is that the concept fully integrates the theme and takes full advantage of it, but sadly can't deliver. After getting food you are never starved for the resources and the clunky controls make the completing the milestones in the blue building tedious.
Besides that there are serious bugs, from the softlock reported by fqwehgtui, to arrow keys moving the player (even though they are not supposed to).
Well done.
