it's unfortunate that it wasn't finished because it's a very cool idea and maybe overambitious for a 3-day game jam! for those who haven't figured it out, you can hold Shift in the facility to show boxes from the past, and then middle click for the drone to pick them up. you can then guide the drone with middle click again, or just left-click and let it follow you. then in a good position, press Q to ask the drone to let go (without holding Shift). however the physics are problematic which makes it impossible to complete
i've seen this type of mechanic before but it's actually quite interesting that in your game, only the drone gets to change things in the past, yet your present character gets to CHOOSE if those remnants should physically interact with the NOW or the PAST, in real-time. with more moving parts and drone commands, you can set up some pretty mind-twisting parallel puzzles this way. good job!
