I liked the game. I had no clue what was going on with the boss. First I though I needed to collect presents. then I figured it out. Boss is kinda challenging. I managed to go out of the level by placing blue boxes near the boss. I don't know if those are meant to help you fight the boss or just shouldn't be there but I used them in my favor :D I really enjoyed the blue boxes feature in general. Gave a different strategy perspective in the game. Good job.
