Simply by opening the gate with the player on the right and reaching the goal with the other one. I actually didn't realize there was a more complicated solution until reading your reply!

Hahaha! Well, you did a really good job at that!!! I'd imagine that someone who plays a lot of sokoban games would be used to tricky tasks like that and would do trial and error until they successfully maneuvered the white die to the gate, but as someone who didn't know what "sokoban" meant 15 minutes ago, I just went "wait, is this even possible? uhh let's see if there's another way" and found the easier solution. It's such a clever mind trick
