Thx, I made it! I got rescued one man! ;-) So why not to write about this on the main game page? Would be more clear for players.
And then went to the left, deep down and found another heliport. Nice it "saved" my position, yeah! But I know why is so hard to play - I play on web :P with super small window only. Pls consider Linux version, probably it's just one more click in Unity.
Anyway - for "some" reasons I like the idea. I think you could make it more playable, but this is your game, your shoes ;-)
