Picture this: you move into a new apartment, and before you can even unpack, you get transformed into a mouse. That is the setup for Mousebusters, the pixel art horror adventure from developer Odencat, which now has a firm PC launch date. The game arrives on Steam on June 11 for $12.99, with a Nintendo Switch version planned for a later, unannounced date.
If the name Odencat rings a bell, that is because the studio previously worked on Mouse: P.I. For Hire, another mouse-centric adventure that leaned hard into its distinctive art style and atmosphere.

What you are actually doing in this game
The premise is equal parts charming and unsettling. Your unnamed protagonist moves into an apartment complex, gets turned into a mouse by mysterious forces, and teams up with a shadowy figure called the Chief to deal with the evil spirits haunting the building. The Chief also hands you a raygun, which is exactly as fun as it sounds.
Exploration takes place room by room across the building's various residents, each with their own story threads and interactive challenges. The combat system, which Odencat calls EEB (Exciting Exorcism Battles), has you cancelling out spirit attacks while targeting weak points. It reads like a mix of bullet-pattern awareness and reactive timing, the kind of system that sounds simple until a ghost starts throwing curveballs.
The game also includes difficulty options for the battle sections, so players who are more into the story and exploration side than the action will not hit a wall.
Pixel art, minigames, and a very chatty mentor
Odencat is leaning into the variety here. Beyond the core exorcism battles, Mousebusters features minigames, parody moments, and a lot of back-and-forth banter with the Chief. The pixel art style gives the whole thing a retro horror aesthetic that sits somewhere between cozy and genuinely eerie, which is a hard tonal balance to pull off.
The studio has also confirmed that streaming is fully welcome, which makes sense given the game's mix of comedic writing and visually expressive combat sequences. Content creators will likely have a field day with the EEB segments.

A small game worth watching
At $12.99, Mousebusters is priced like a confident indie with a clear sense of what it is. The combination of horror framing, accessible mechanics, and strong visual identity puts it in the same conversation as other short-form pixel art adventures that punch well above their price point.
For players who enjoyed the rubber-hose shooter energy of Mouse: P.I. For Hire, this one scratches a different itch but shares the same love for mouse-sized worlds with outsized personality. Mousebusters hits Steam on June 11, and the Switch version will follow whenever Odencat is ready to bring it there.
