Snake game

So I decided to create my first snake game. But I would like to generate obstacles on the level.
The problem is that there could be situations when obstacles create some corridor take a look at the schema to get the idea https://monosnap.com/file/EaW1gyGA5pQFAiLwEfgZjUqqxPATOq
In this situation, there is no possible way to eat the thing by a snake and do not die.

So I would like to create some kind of a map of the level and script, which can understand where on the level are places to safely put the snake food item.

And right now I have no idea how to do that. Any guesses?

 

I would just keep it simple, and require that the food always have at least 3 empty spaces around it. That, plus not using a lot of long skinny obstacles, should make it almost always possible to get the food.

If you're still bothered by the very low chance that an impossible level is generated, then you might want to give the snake some way to eat through an obstacle, but make this a special trick it can do only once per level.

 

Thank you! Yep, today I woke up with the same idea about checking space around the food.

 

Ok. Next challenge. The cubes I created have very dark sides and I dunno why.
The light settings are default.

I do...

That's why.

Adjust the lights to your lighting. The default lights are pretty stark.
