It's not working for me, tried Firefox and Chrome, the playfield is just a white box.

Sorry, couldn't run this - I think due to it being on dropbox (it fails to load content from a different url).

Game working fine here, the javascript alerts were pretty annoying, game was hard to play.

Nice entry!

Ok, now the corrected link should work. Sorry, i had problems with dropbox...

OK, works now, but seems impossible to avoid red things, there's no warning and they come quick. I got a huge score by going all the way to the right and hitting space a lot. :)

Nice game, even if it's a little bit difficult to avoid the red square :(

Very unique, but confusing.

That _was_ silly! Went pretty fast, don't know if I could have avoided red. Not really any feedback when you get hurt.

Very challenging, trying to figure out when not to jump, when to move, etc was good fun. Got some laughs out of acellerating rapidly.

Agreed that it's really challenging, mostly because there's no way to know what's coming up ahead of you so you're destined to slam into the danger zones. Perhaps if the objects were farther apart from each other depending on how fast you travel it would be a bit easier? Also if you stayed closer to the bottom of the viewport it could give you some advantage as well?

Simple and fun!
I found it a bit difficult to get anywhere without hammering like crazy :)

Fun little game, I got to 18000 by jamming the space bar until I had one life left (:

Simple, but effective. Once I realized that "don't jump here" means "you can jump into here, but don't press tap WHEN YOU'RE IN HERE", the game was more fun. I would've liked to see forward a bit more, otherwise going fast was really just a gamble. Still, a really neat entry!

Ok made some fix & update!
Thanks to all of you for your feedback. Hope know it's more playable.

nice idea & nice game :)

Fun game, for quick play!

I only wish the red blocks wouldn't keep materializing directly above the green blocks. ^_^; Also, the collision detection seems slightly inconsistent - I can jump on the edge of a white block without damage, but I can also get a boost brushing the side of a green block, and touching a red block anywhere is, of course, death.

Decent concept, but I would probably change how the jumping mechanic works. Right now it's usually so safe to hug the right and left sides of the screen while periodically mashing the spacebar that it breaks the game. Maybe you could have it so the player has a variable amount of jumps that increases every few seconds, while the screen gradually rises?

Just a suggestion, good work overall. :)

I kept dying because the green boxes sent me straight into red boxes. Nice jumping mechanic, on the other hand.

Way tooooo hard :)

nice game, very funny

Simple, but effective. A nice idea, well executed. Good stuff.

Liking it.
It's bloody hard to avoid the red boxes but not frustrating or game breaking hard
It'd be cool if the falling speed was slightly slower - or maybe I just don't have the skills! :)

The highest I got was just over 106__.

Firefox kept telling me I needed a plugin though?

A bit random because it's too fast to know what's coming up, but once I got the hang of it I got to 43,000.

This was fun! The controls are too stiff, though. Moving left and right should be faster, and the speed gained by jumping is too unpredictable.
Nice take on the jumping vertical platforms game.
