White slows just the reds by 50% for 5s. When it is active and you get another white, you refresh the 5s timer. Also, as time passes, the speed range of the reds decreases, but they spawn more frequently.
Green doesn't stack, so getting another when you have the shield does nothing.
Yellow gives you different extra points depending on how long you've been playing. Longer playing = More points.
I've also been adding additional power ups for future versions like shrinking your player size for 5s to make it easier to dodge in the later stages. :P
This was also my first idea, but instead of force, I was gonna play with sound (how loud the steps are). I wish the restart when you die is a bit faster, but very nice bgm and sfx!
Reminds me of the classic "Game & Watch" games! I agree, it's missing a command to fall faster so you don't feel as helpless with the random nuts below. Or maybe you can have the ability to jump again midair when gathering a new leaf? I like the wall restrictions and good job on the sprites!
