This is totally awsome. Brawlhalla is a smash clone with limbless characters, so rayman would fit right in.
Brawlhalla is also a unique and fun type of smash. Its biggest difference is its weapon system. Every character plays the same without a weapon, but as the match progresses weapons fall from the sky. If you pick up a weapon you randomly get one of the two weapons your character specializes in. This changes your moveset to make you stronger, but there is ways you can lose it. If you get hit hard you will drop it, or you can throw it at your enemies. You also lose it if you are KOed. The other big change is thier wall jumps. Wall jumping is extremely easy, which makes it much harder to KO without jumping down and spiking for the KO. It’s pretty good.
