Snake is a great time filler and this is pretty alright for what it is. But the keys are a bit unresponsive which kills some of its fun frankly, if not for that this would easily have got a 4.
On of the very first games I experienced for the Spectrum (on the 16K!), Slippery Sid is a noteworthy example of the classic "snake game" which becomes harder and harder as you go on. Still good for a few goes every now and then.
