oh wow thanks so much for the video!
i see now, so the plug thats going into the socket is always gonna be the last plug that entered its range (the while circle), and also it has to be inside that white circle to pull it! i see that it can be really confusing though, there should be clearer visuals to show which plug is going to be pulled if you release the mouse buton
SPOILERS:
your strategy is correct! the only thing missing is that you can actually jump from the left plug connected into the socket into the safe platform on the right (if the staircase didnt get you far up enough), and then after jumping there you can safely aim at the bottom left socket to connect the other plug (thats connected to the top socket) into it, then opening the door. where mag is only affects where the plugs will land when you pull them, you dont have to stand close to sockets to plug them in, though i can also see why that can be confusing and that wasnt explained at all either
also dying when jumping on top of a plug is really frustrating, that shouldnt happen and thats the kind of thing thatll really frustate the player out of the game, especially in the last level after working so hard to get through the first part, ill fix that ASAP
thanks SO much for the video and feedback, its really invaluable, seriously!
