Initially got confused because the description said to drag items from the side, however dragging just scrolled it. Eventually read on to learn that dragging means click and click again ^^” Was an interesting experience and nice to see some more realistic stats! The game just kind of forces you to idle it for a while because the upgrades are so expensive. I only bought the golden cockpit (twice, because my ship exploded due to mass limits) and got to an altitude of like 60. Still was fun to check this game out!
