Awesome idea and art. When I was brainstorming ideas this was one of the ideas I considered, but I opted to make retro Asteroids with roles reversed instead. I think this snake idea has a ton of potential, but it is too luck based and there isn't a clear goal. If this was turned into a puzzle game I think it could actually be super awesome. Different levels could have different spawn points, different number of lives, levels have obstacles or different shapes, multiple snakes with different speeds and/or movement patterns, maybe even have special mice with different abilities.
