HEY! I know you! lol I was JUST thinking, "Isn't it a shame that Wym won't be able to include those great games they made before for this jam?" and here you are! You put so much work and imagination into making your stuff and this is no different.
Very much in the vein of those "destroy the box" board games (or whatever they're called now). It's poignant and direct. We overuse the term, "Hero" nowadays and I often remind people, "You know in the old stories the hero often ends up...dead...right?" Sacrifice is integral to those stories and the idea of truly being a hero, and it's great that you chose that as a theme.
No notes from me on this one. It's so tactile. I think this is one people could play in less than half an hour if they wished. Very much about the experience.
