My only qualms with this game...
Honestly, there are 2 things here that bug me- the first being a lack of pause button. If there is one, it's none of the usual buttons. It makes this game frustrating in that a friend called, but I didn't want to stop playing to answer the call. So, with no pause button, I was forced to ignore him.
The other issue is that, from time to time, a momentary and absurd loss of control would send my snake headfirst into 3 or so demons. I'm being as delicate as I can, and still it happens. It breaks the experience a little by making it more a test of patience than a game.
Otherwise a very fun and absorbing little flash. The final boss, while very slightly annoying (couldn't get my tail out of the way of the many demons), was very stylish and well designed.
The whole game was like that- very sleek and a pleasure to watch. When my snake had a moment to stop, it was quite amusing to see his face shifting about periodically.
9/10, 5/5. Work out the couple of bugs and you'll have a real winner on your hands.
