I might be wrong, I’m new here just trying to be useful in community.
When the character (let’s name it Bob) starts to get the boost to start walking/running it seems that Bob is already walking/running before the boost so it doesnt feel sooo natural, try to stretch more before the walk/run and only walk after the boost.
Sorry about the low quality english, I’m just trying to help.
By the way, I love it, Keep going on.
