Fun game! Love that you themed your itch.io page to match the game, very cool! I liked the screen-shake and SFX when you shoot, made it feel very visceral. It would be nice to have a similar punchy feel when you killed bad guys - as it is, it doesn't feel as cool to kill one. Love the walls of the levels. Wondering what makes it a "one room" dungeon, since you go to other rooms? Minor detail though. Also, it wasn't clear what benefit I get from rolling, as the movement seems unchanged - is it a temporary invincibility? Great job overall!
