Air Dash Online is very, very similar to another party fighting game franchise that has basically taken the genre to an entirely new level. That franchise is, of course, Smash Bros.
The devs behind Air Dash Online, JV5 Games, specifically cite Super Smash Bros. Melee as inspiration for their 2.5D brawler, while also taking elements from Dragonball Z and Guilty Gear.

Air Dash Online is actually getting a kickstarter, which will be launching later this Friday, October 11th.
