My New Game Monster Mayhem Launches June 27!Hey everyone!
Im super excited to announce that my next game, Monster Mayhem, will be launching on June 27 on Steam!
Ive been working solo on this project for a while now, and if youve enjoyed any of my previous games, I think youll really enjoy this one too. Monster Mayhem is a fast-paced 2D survivors like game where you fight through waves of monsters, unlock unique heroes, and take down huge bosses all wrapped in a colorful, cartoonish style.
If youd like to support a solo dev, the best way is to wishlist the game, it helps a lot with visibility on launch day:

Thanks so much for all the support, it means the world to me. See you June 27!
