Optimizing, optimizing, optimizing... I'm finally able to complete the VTOL in my attempt to do this in as few loops as possible. Messed up and forgot the engine so will have to redo the longest effing loop I've ever done where I go to every single area the long way, which I didn't even know for sure was possible until now. Loop 21.
After taking a break from the game and returning to this I figured out I messed up a bit and went back a few loops. Ended up getting the VTOL prepared and ready on loop 18 instead! Only major thing I haven't done in this optimization attempt is scanning the propeller, but I'm all set to do so the next loop. Looking forward to the next update!
