Shift + Alt + Numlock = Mouse Keys for those of you with numpads. Once enabled, hover over the ore and mash 5 and + on your numpad to click very quickly. If it doesn't work, try pressing numlock and trying again.
Nevermind I beat it. If you're having the same trouble here was my combo:
Head: Mark-V-AH
Body: Mark-V-RE
Fins: Mark-V-A
Engine: Mark-V-P
Boosters: Mark-V (The Last One)
Misc. Items: Radar-2, Built-In Cistern, Refueling, Device 1
Goal: Aim for acceleration gates and fuel pickups.
I love the game, but does anyone have any tips on completing the space cargo mission? It's the only thing between me and the hard badge... I've bought all rocket parts and tried lots of combinations, but I can't get higher than 200k/300k.
