Really good idea to have the game running while on the tutorial: the player can test how the controls work on a safe space, nice! The gameplay was interesting, fun and challenging, but after the third level the difficulty spiked really fast. I couldn't beat the fifth level =(. I know it's hard to balance the difficulty of a game but I recommend to playtest with other people next time, just to see if it's too unbalanced. Other than that it was a very fun game!
