Very addicting and fun game for a very important historical event, good job. I managed to survive under 100 seconds and throw about 10 crates at the sea. I just think the difficulty is a little unfair. What I would make different to balance the difficulty is to make the guards a little slower than the player and make the player slower when grab the crates, or keep the guards speed and indicate their next movement so you could know where they are going before they move. But that's just a suggestion.
