Great work on the visuals the telegraphing of the snake's entry is particularly good, some really good squash and stretch. The snakes themselves are also excellently done, with the screenshake and the particles whooshing past at incredible speed is really effective for making them feel like they're going to do more than just take a bite out of you.
The first level is a great sort of tutorial introducing to the ways the snakes can come in from the sides as well as a group taking out a bunch of bites at once.
I think the second level is the hardest, it can be a little unclear where snakes are going to be when there are multiple attacks being telegraphed in the same place, as the snakes can cover up the indicators for where the next one is going to be.
I think the music is a great fit and I was jamming along to it while playing the levels, at it feels thematically in line with the goofy looking snakes.
Well done!
