I almost love this game, except for one thing: the damage system. There should be a cool-down period when you take damage where you're invincible (briefly knocked backed as well perhaps). As it stands if I so much as touch a snake for a microsecond I'm down from 100 health to 40.
Another issue is that the player moves a bit too fast, I eventually kinda got used to it, but it would be much more enjoyable with a slower speed. The imprecision of the movement due to the high move speed actually worsens the major problem I have with the game, since it's harder to control when you're moving so fast. Makes it too easy to accidentally hit something and lose half your health. Which feels really unfair.
Good game besides all that and I'd play it much more if it weren't for those things. I just simply die too fast because of them.
