It's a decent little concept you got there.
Would like to be able to remove the tiles you place after you place them and for the "snake" to grow.
Also it doesn't really fit the holes theme much, but i like the idea of it.
Thanks for playing my game. I'm glad that you like the idea.
The "snake" should be able to grow, unfortunately I was running out of time to implement it. I think making the tiles (actually they're holes) unremoveable can add more complexity into the game, that the hole player dig right now might have a long term effect, so that player should think twice before placing the hole.
