Created platforms issues

I've got an autounner game and was working on the platforms. I'm using sprites for my platform rather than tiled background like the autoruner template.

The game gets gradually faster and the problem i have is that the created platforms sometimes overlap each other, especially when it becomes faster. Also sometimes that gaps between the platforms appear too big as well.

I liked the way the autorunner template worked and tried to use that for my one, but i'm getting the issues i've mentioned.

Ideally i'm looking to create the platforms so that the gaps between them vary, from small to bigger gap.

Thanks

Thanks for the example, although this is a little more complex than i expected

I will try to work with the capx you provided but ideally i'm looking for a method that uses bullet speed to control the speed of the platforms as my game relies on bullet speed, similar to the example i provided.
