I have tried a few of Jupitrons games, and I must say, this is actually weirdly addictive.
If you get around Jupitrons logic, its quite fun!
I can see how someone can get a high score in this- namely, u must jump on top of the enemies head DIRECTLY IN THE MIDDLE. If successful, you will progressively jump higher and higher. This is def possible if you jump on the green enemies, but harder on the floating shoalin monk enemies as they move slightly faster and don't have a lot of flat space on their heads.
If you want to get a really high score, you need to be semi-perfect and KNOW THE PHYSICS OF THE GAME. I got 23 after a few goes, but stopped shortly after.
I love these games. They are actually well made and designed and simplistic, yet addictive and hard!
I would...liken your game to 'dark souls' of the new ground worlds. It is hard, but once you get it, it becomes quite fun!
However, I reckon a bit of background music would of been quite good!
As always, great job Jupitron!
More more! :D
It also reminds me of that classic mario game where you jump on heads to get higher and higher. Another classic nintendo game that has the same feel is 'Climber'. There are others, but this is a much better version. Maybe a few more layers would of been good but heck, its good enough! :D
ps- i reckon you should make a long game which is hard, but as good, like your other game, 'otherworld', which I think is greatly misunderstood!
GO PLAY THEM!NOW!
