Mewfuse: Room Stack

This cute and relaxing cat merging puzzle game brings you tons of fluffy fun. You need to launch cats of various sizes into the storage box one by one. Whenever two cats of the exact same size bump into each other, they will fuse together and turn into a single bigger cat automatically.
Pay close attention to your placement, because the game will end instantly if any cat slips and falls outside the box. You can freely drag any cat out of the box with your mouse to adjust your layout and make more room for new cats.
From time to time, little mice will appear on the screen, and catching them rewards you with extra special chances to rearrange your cats. Keep merging different sizes nonstop, unlock every unique cat shape, and see how huge your ultimate cat can grow!
