The sound effect of the player shouting is very funny!
At first I found the game unfair, because without knowing what the next obstacle will be, you can't calculate the exact height to let go of the rope, but after a while I started using a “short rope” technique to go more slowly and see the challenge ahead.
It worked well for me, it's how I managed to get further, but I still didn't get anywhere near the records.
Another thing that struck me was how fun the game is, even with its simple graphics. Nowadays, AAA studios spend a lot of money on realistic graphics, while a monochrome game that does the basics is more fun.
Congratulations on a job well done!
