Looks and sounds great. What a soundtrack!
Plays really smoothly.
I think there needs to be more clarity about what each region of the HUD does when you click it with the gauntlet. The "crackling electricity" VFX is exactly the same no matter what the glove touches, so that really doesn't distinguish the regions.
My suggestion actually would be to add a little note in the game description: Drag coins to the bottom right. Charge the gauntlet on the top right. Charge the battery on the center left. Etc. Either that, or little labels or tooltips.
