Nice entry. Your title screen is very pretty.
I found it a bit difficult to see the bullets and therefore dodge them, but the 'worm' feels fluid and nice to control. It's a shame that the 'worm' aspect doesn't add anything to the game mechanics though, as it doesn't deal or receive damage.
Perhaps if it received damage it could be like a risk/reward thing where you're more at risk if you stretch out to attack. Or if it dealt damage, you might have to wrap around a victim instead of simply touching them.
