Nice game, the music and theme interpretation are really good here. Like others have mentioned, moving from square to square could be a smoother experience and was disorienting at times. I died way too many times because I was unaware of the fact that the snake was even moving when I wa sup against the wall.
I also expected myself to die every time I was near a bomb until I realised only the head takes damage from bombs. I wasn't sure if that was intentional, but maybe it would've been better to have the entire body affected by the bombs?
Apart from those, this is a really fun reimagination of a Snake game. Great job on this one.
