Nice, short puzzle game.

I am not sure for which platform this game has been originally been developed, but the input methods would make it a good game for touch devices like smartphones. All the tutorials explain the controls with swipe gestures, but actually you can use the arrow keys of the keyboard and probably the joystick of your gamepad.

Anyways. I like the game. Didn't take me too long to finish each puzzle, some were easy, some were hard. A few were solved by using the hint button that replenish over time.

It was weird, that an ingame achievement icon was poping up from time to time, but there is no overview in the menu or steam achievements available. Would be a perfect addition to the game.

Also this game is needing a level editor for us to design puzzles for our friends.
