Jump not working right and run speed gets progressively faster

The controls respond but the output is not right. You can see that it tries to jump but never leaves the platform. When I run, the speed does not cap, so it gets increasingly faster. Any ways to go about this?

Wow, that's... a whole lot of things you want to do sometimes, but you're doing them all the time. A CODE block would really have helped with the indentation, but another thing that would help would be to put the checks inside other checks where they belong.

And you really don't need to check every input twice per step. Once is plenty.
