I saw this in F3 and thought it looked awesome! After finishing the demo I can say it was even better than I first thought! Can't wait to see more from this! If you are taking feedback then it would be nice if there was a persistent UI element that showed which element you had selected, like maybe just a small icon above the health. Bogmire's fight is extremely loud, compared to the rest of the game. It would also be neat if the 1-up mush had text that told you that it increased your max health, like how the poltergust does.
