Well, the snake is shown on screen all the time, the whole point is to keep an eye on both games. They are simple, but all becomes a lot harder when you need to constantly track both.

And also, in Tetris, we can somewhat choose stress time – we can drop a piece or keep it falling by itself and take this time to check the Snake. And in Snake, there is no way to speed it up or slow it down, it is like a clock (the SFX has a ticking sound). I also find myself doing simple mistakes all the time, but after some couple of concentrated tries I manage to do 40-50k+ points :P

P.S.: Thank you for the feedback <3
