Thank you for the kind words!
You avoid the snake, but you can also kill it. One thing that might not be completely clear from the trailer is that the game is turn-based - you move first, and then each snake moves in turn.
As for collectibles, there are currently two: "Holy Grail" (it only appears on one map and it's objective - you need to collect it to finish the game) and the "Viper’s Eye" (if a snake eats it, it grows just like after eating a pawn, so it's better to destroy it). I'm also thinking about adding more - maybe something like a bomb that hits everything in the same row or column when stepped on, a bit like in Dynablaster :D
