Leaving Early Access: 2027

What the developers have to say:

Why Early Access?

“Mussaverse The Game is the next chapter of the project previously known as Mussoumano: Attack of the Haters. We are reworking the adventure and want players to take part in its evolution.

Early Access allows us to gather feedback on controls, difficulty, level pacing, and the overall experience, helping our team identify issues and guide improvements throughout development.”

Approximately how long will this game be in Early Access?

“We do not yet have a revised release window to announce. The transition from Mussoumano: Attack of the Haters to Mussaverse The Game involves a substantial reworking of the project, and we are reassessing our schedule accordingly. Our previous estimate no longer reflects our current plans.

We will share a new estimate once we have greater confidence in the remaining scope and the time needed to complete it.”

How is the full version planned to differ from the Early Access version?

“Our goal for the full version is to offer the complete Mussaverse The Game campaign, including its progression and conclusion. Along the way, we plan to expand and revise the adventure’s content while improving gameplay, presentation, and performance.

The scope and order of these improvements may change during development based on testing and community feedback.”

What is the current state of the Early Access version?

“The current version of Mussaverse The Game includes the first level of the reworked adventure, available to play now.

The previous version, Mussoumano: Attack of the Haters, had 15 playable levels. As part of this overhaul, we are revising and adapting that content to the game’s new direction. This update therefore offers only the first level, and we plan to release the remaining levels gradually, one at a time, as their revisions are completed.

This version does not yet include the full campaign. Player feedback on each level will help guide adjustments throughout development.”

Will the game be priced differently during and after Early Access?

“We intend to increase the price when the full version launches to reflect the expanded content and improvements to the overall experience. We have not yet determined the final price. Any price changes will be communicated to the community in advance.”

How are you planning on involving the Community in your development process?

“Players can share suggestions, report issues, and discuss their experiences in the Steam Community discussions.

We are particularly interested in feedback on controls, difficulty, clarity of objectives, and level pacing. These contributions will help guide adjustments and development priorities. We will also share development progress and major changes through announcements on Steam.”

About This Game

A modern tribute to ’90s classics — packed with action, platforming, and the chaos of the Mussaverse!

W, Mussa’s reverse counterpart, and his Wloids have invaded Mussa’s universe and turned everything upside down! Now Mussa must embark on an adventure across different worlds to take on the invaders and put an end to the mayhem.

Mussaverse The Game is a 2.5D action-platforming adventure that combines 3D environments, challenges inspired by ’90s classics, and the humor of Mussa’s universe. Get your microphones ready, time your jumps, and dive into the adventure!

More Than Just Jumping

Different stretches of the journey bring different ways to tackle the challenges. Throw microphones at enemies, ride a camel, slide along rails, swim among piranhas, and brave sandstorms. Between platforms, obstacles, and changes of pace, Mussa will need more than a well-timed jump to keep moving!

W Is Here. And He Brought Company

Mussa’s reverse counterpart didn’t come alone: his Wloids are spreading chaos throughout the Mussaverse. Beyond the invaders, the worlds’ own creatures and traps make the journey even more dangerous. Watch your enemies, choose your moment to attack, and mind your next step!

Old-School Boss Battles

Formidable foes, attack patterns to learn, and openings to strike back. Boss battles put your skills to the test and bring back that satisfying feeling of figuring out a challenge after a few attempts — and finally winning!

Master Every Level

Pay attention to the details, discover better routes, and learn to overcome each obstacle. Collect coins, stock up on microphones, and make the most of the resources along the way. Knowing a level inside out can make all the difference between falling short and reaching the finish!

A New Adventure in Mussa’s Universe

Previously known as Mussoumano: Ataque dos Haters, the project enters a new chapter as Mussaverse The Game, with a reworked adventure and W at the heart of the chaos.

Early Access

The current version includes the first reworked level. We plan to add the remaining levels and their mechanics gradually through updates. Share your feedback in the Steam Community and take part in this new chapter!
