Side scrolling combat reminds me to "Spirit Engine". Perhaps the combat terrain doesn't match what it seems from top down exploration.
The combat is meant to be that of Paper Mario. Turn-based, low numbers, enemies on the ground or airborne, equippable badges... that kind of stuff. Spirit Engine looks interesting from what I've googled, I should try it out. Hopefully I'll be able to thank you for making me discover it ;)
The floor in combat is a placeholder. I haven't taken the time to mess around with battle backgrounds yet. My priorities aren't always where they should be x)
