Nice game, Simple and fun, i have some small comments that in my opinion would elevate the gaming experience even more.
1- I noticed that the character start jumping after i left my finger from the space key, which mean the jumping logic in your game is triggered with OnKeyUp, in games fast response mechanics like jumping usually are implemented by using OnKeyDown, where the character jumps as soon as you push the button not after the button retracts.
2- Maybe change the color of the platforms a bit because it some times blends with the background which make them hard to see.
3- Maybe increase the speed of the platforms with time. (i don't know if this is already implemented or not but i reached 1252 score and i didn't feel that the speed has changed).
4- Maybe some sound effects and exciting music will also be great.
Don't take this comments as a bad thing, i really like the atmosphere of the game i just feel with those comments you can unleash the full potential of this game. :))
Great Job overall :))
i would love you to checkout our game and maybe give us a rate :)
