This is a really cool concept and actually a very unique one. I don't think I see anything like this during the jam. If you polish it up I think you might have a really good game to publish. I know som eof these things were probably left out because of lack of time during the jam, but anyways, some suggestsions:
- A tutorial woul have been good for the "jump" I got stuck in a valley and had to figure out myself that the snake jump higher if its starts from the ground.
- Maybe a timer of some kind would be nice to see how much time I have left before the night comes.
- definetly add sound to the game :)
But very nicly done, good job!
