Is there a way to change the gravity?  I'm a bit sketchy on the details of the game I guess.  I am pretty consistently hitting the cart from the top of the screen every time and nothing seems to change anything. Also, sometimes I get a score or thumbs up or whatever in the bottom left in the first position, sometimes it begins in the third position, etc.  I don't understand that.  Thanks!

thanks for your report!

I confirmed there is a bug where the amount of gravity doesn't change according to the difficulty level. And, depending on when the game starts, there are times when the number of "stages" changes to be incorrect. I am working on fixing these issues!

possibly related to gravity, possibly a different bug entirely, I have had several times where the man falling out of the helicopter does not fall, he just hovers in place, or even flies upwards slowly, never to come down. This usually happens after I've finished the first level or two of difficulty.
