The idea is awesome, and it plays really great, congrats!
It took me a couple of attempts, but when I managed to take five back to the helicopter without dying, nothing happened? Still, even if the end was a bit anticlimactic, I quite liked it <3
That's weird. I did mention on the games page that certain triggers are a little bugged, and that you had to press C when at the helicopter. Probably should have put that information in the game, but I was rushing
