Happy Grumps is a love letter to classic roguelike adventures with a twist: instead of trying to steal treasure or fight monsters, you are on a quest to spread happiness to a grumpy world.
A game about happiness?
Glenn was working too much. His family was slipping away. His health was failing. And he was grumpy all the time. He made a promise to his family to get less grumpy. He quit his job to be a stay-at-home dad and make games.
"Happy Grumps sounds a lot like something society needs right now."
-Forbes, Matt Paprocki, 'Happy Grumps' Is Out To Make Us All Happier
