Hey RockyRockford, thanks for the compliment!
You could definately lock the gravity to just one axis, but this has to be done in version 1.1 that should be up very soon, we sent Epic the upgrade a week ago. I tried doing it on Unreal Stick Figure 2D and it worked perfectly.
As for the walking effect, you wouldn’t be able to do it with this, because it has to do with the Character Movement Component, and it would involve C++. We’re doing it all in BP.
However, here’s a link to a free plugin made by Mhousse1247, you could try it, it looks like what you want.
