This game is hard, stressful, buggy, and just not very fun to play. The enemies have a huge unfair advantage and killing them just makes it harder and the only way to win is to stop their bullets with your own or do the painstakingly long task of repeatedly killing them until you can drag the buggy boxes all the way there, and theres RNG
edit: beat it, but only because the enemy got stuck on the box for a little while giving me enough time to drag the second box there
