Very cute game. The art and music is very charming. The tone of the music, and especially the chimes after victory and stuff really sell the atmosphere you're trying to set, I think. It's kinda funny how you can keep swinging after you die, cuz you're the sword and not the grandson. One thing that was very frustrating for me though, is that this game really encourages you to spam-click with the gameplay, but after you die, the death menu pops up and I would accidentally click the menu button and lose all my progress. I got a handful of levels in at least 4 times before I couldn't do it anymore with restarting from scratch.
Cool concept, though. I'd love to see cute interactions between the grandpa and the grandson, I think that would really capstone this experience.
