Pretty decent. That is what i like to see in UE4 games. Was it inspired by arena shooters like Quake III, Overwatch, Apex Legends? Unusual to meet something like this in Jams, this is great. +Recommend.
But hey, no title screen, no menus, no level streaming, you just drop the player into arena (not even at the safe spot) and say "Go Fight!". It definitely should be added in the future. Keep up the great work!
