Not much effort here so don't expect good reviews.

One thing. You could make this less of a shit game if you raised the speed already at the beginning. That way it might pass as a low quality reflex game.

this game needs all these things to get atleast 1 star
1: actual graphics
2: some difficulty
3: some time put into making it
4: not having the score in a very odd position
(i think i use the same program the creator did and all those things are easy to add)

After a certain point it keeps coming at the same speed, i think the speed stopped increasing after about 10 levels i suppose.
And i waited for about a 100 points, hoping it would get faster .
But it was the same.
So i killed myself and tried it again, this time the speed remained the same when i started from 0 and then the speed slowly reduced from level 6 onward.
Then it again gained some speed after say 5 levels and then stopped increasing.

I suggest you increase the speed in steps also try reducing the area of the red platform a few pixels for each 5 or 10 levels.
This would probably make the game more challenging.
Maybe add in another line that follows the first platform so that the player needs to get to one red platform and simultaneously get to the next platform that follows the first line.
You could also decrease the size of the blue box to increase difficulty.

Just my opinion.

There is always room for improvement, and always an 'A' for effort !
Good luck further !

way too slow. i got bored at 300. try to make it more difficult!

I like the mechanics there are very addicting and fun but i would move the text up and get a game over screen and not just reset the text that barely anyone cane see.
