Vampires and zombies will be coming soon. As for side scrolling it currently does not have proper walks or runs as they're all mostly stationary moves for rpg battles.
To be honest I cant say how soon or for sure as I have a lot of other things related to store and commissions on my plate which have me tied up for the near future. I don't want to promise anything I can't deliver reasonably soon. That stuff would be bonus content to packs that I try and do every so often
