Such a unique and funny premise! Playing as a reaper mowing down hair on a scalp to increase someone's Norwood level is genuinely creative and memorable for a jam.
The mechanics like charging the scythe throw and managing combos give it a nice action feel. As a minor feedback point, the text overlays in the top-left (stats like scalp coverage and time) can be a bit hard to read against the skin-toned background. Adding a subtle drop shadow or background container for the UI would improve readability instantly.
