About the game
Mousebusters is a pixel-art adventure that casts you as a tiny mouse exorcist creeping through a ghost-filled apartment building. The goal is to free its charming, oddball tenants from whatever haunts them internally; the game is also listed under the name "Mouse Busters." Odencat both developed and published it, available since 2026.
