Wow, now I am really surprised with your feedback. You are actually first one who have such problems. But the tutorial is the main page, where you are basically forced to try all the controls that you will need in the game, let me summarize that. The game is an endless runner, so you have a character, that is "infinitely" running and you need to overcome all the obstackles in your way. The twist is, that at the same time you need to complete the jig saw puzzle, as if you don't you will not see much. 

Left mouse click to pickup a puzzle piece. Right mouse button to put down the puzzle piece.

To control the runner you need your arrows. Left to run left, right to run right and up to jump.

But really all of it can be found in the very first scene ;) Let me know if this helped! And thanks for trying my game
