Jet Drive Engine can be easily overlooked

[Dunkler Messias]

I just ended the game without using the Jet Drive Engine since neither the travelling merchant nor the shipwright sell those after I researched the engine.
Well, turns out they are in the shop but I never found these since they appears in another U shaped engine.

So, maybe use the whole trading window, so the different engines are more visible. Or at least next to another engine, not filling a slot of an engine with the size of 3 or 5. :-)

Dont blame the Game for your bad Eyesight ;P
The unlocked Equipment gets shown in the sequence they are unlocked. You seem to have unlocked the twin-jet and then the Jet drive. Since the Game is basically Tetris, it will place the new unlocked Equipment in the next avaiable Slot, from top left to bottom right.
