"Help Mauri Mursu on his adventure
on the Walrus Islands
and cure his hangover!"

Mauri Mursu's Hangover is a new 8-bit homebrew game for the NES in 2022! The game gets its inspiration from adventure game classics, such as StarTropics and Zelda, and mixes in a lot of quirky off-beat humor and quests. If you are a fan of those games, you will love this one! 

So, what are you still waiting for?

The BIGGEST Walrus Adventure on the NES awaits!
