Nice job. Honest feedback:
*** Positives ***
- Having a warning icon where enemies are coming from is a nice addition
*** Negative ***
- When going up the snake appears to be randomly wearing "shades".
- Did you test the laser emit point from all cardinal directions? Because it's not coming directly from the snake's mouth when moving up or down.
- Viewport resolution detection is messed up. The game properly scales but then asks me to "Rotate my device" despite being on a full desktop computer.
*** Other ***
- Snake comes with a set of expected conditions from players given its popularity. At first I was very confused why there wasn't a static item always on screen that would cause the snake to grow. Instead it appears to be time-based? Or possibly one of the bugs you eat?
- You may want to make the boundaries more explicit with physical walls. I honestly thought it was going to be like asteroids where the game wrapped screens.
- It's far too easy and the difficulty takes too long to ramp up. I would tune it a bit.
