Hello @Peteryim it looks like you make a lot of posts like this that get deleted. You're not in trouble or anything, but I would like to take this opportunity to just let you know that while these videos are great and you can feel free to share them, you really should try to add some sort of discussion points to prevent them from being taken down.
I'm gonna leave this one up, because it looks like it has its own inherent ability for discussion, but please keep this in mind for the future!
Personally, I think there is a sort of ambiguous level progression in each episode. Although it may not be explicitly "levelling up," we get visual cues such as her armor and weapons that let us know she is gaining power. I'd say she is probably about level 20 by the end of season 1.
