I'm getting a bug where every level when I become a snake for the first time, it doesn't appear. I have to reset the level and then it works. It did work on the double crate level though. My guess is if you hold any direction key while it spawns, it freaks out. I came to this assumption because it happened after resetting on one level.
Another bug was dark crates bouncing for some reason. I think it happens if you manage to push it in mid-air.
I finished the game. It was enjoyable. I liked the graphics and how tight the controls were. I'm going to have to play it again because I cheated on one level with the bouncing dark crate....
Does the game just stay on a blue sky after "The End"?
