I liked using the abilities I got while in combat, maybe to add some variety the rivals could use the abilities of their rings too (for example, on the first map the rival could double jump) . On the final boss I fell off the map and it didn't kill me, so I had to stop playing :(

I originally wanted the enemies to have the abilities of their rings, but I wouldn't have had time to figure out how to make the bots actually jump lol so I just scrapped that idea. Not sure why you didn't die on the boss level, I checked the kill volume and it's plenty large enough. Maybe I should add a respawn button to the pause menu... Thanks for playing!
Edit: of course only a few minutes after posting this comment I figure out a way I could have made the bots jump around haha
