This game is really easy for a puzzle game, which is clear even as someone not very experienced on the genre.

I still enjoyed playing through it, though, since it's quite polished and the Snakebird concept by itself brings some interesting ways to deal with puzzles, even when they are as hand-holding as these ones.

I guess Primer is good enough as a tutorial for the actual Snakebird (which I haven't played yet), but being just that makes it feel a little shallow and bland.
