This game is excellent for the time limit! The main gameplay loop is very fun, and I'm impressed with the number of unique boxes there are in the game! The one issue I have with the gameplay is that the human and robot sides both have the same set of tools, except for the green ones. So eventually I found the strategy of simply leaving the green tool in the robot hand and only switching the human's tools. If both sides had different tools, the scrambling to find the right tool would be a lot of fun, I think.
The only other critique I have of this game is that there is no tutorial. You should never overlook the tutorial in games, they are crucial to the player's enjoyment. I almost gave up because I couldn't figure out the controls. Aside from that, I really enjoyed it. Fantastic job!
