The mini-games are classics, but not much innovation was put on top of it. The art is unique and simple. The game could benefit from some comfort-features that re-makes of the classics have, like making a queue of button-presses in snake (so two quick inputs result in the game inputting those actions on every square), and drawing the snake as a thin line instead of a block.
There's also a bug in the snake game where your snake can do a complete 180 simply by pressing a side direction then the reverse direction really quickly. Results in your snake dying if it's longer than 2 segments.
