Yes, I added the little extra time so the game is more forgiven when there are many jumpers, so wherever they are under certain height you can make them jump :). Thank you for the nice feedback!

Yes, it seems there was also a olg Game & Watch machine called Fire that used this concept but I only knew the old ms-dos game. Thanks for pointing it out, I will try to play the original with some emulator.

And any ratio that goes over 25% is good. Because of the random element of the game, you might end with x / 90-110, and it is pretty challenging to save the bottom row guys as they go much faster :)

Thanks for the kind words
