Hot Barrel Cats

A fungus horde called the Mildews marches down the road toward your gate, and only the cats standing on the wall can shoot. The game pits 15 tiers of barrel-toting cats against 5 kinds of Mildew. It is single player, with 16 hand-tuned levels that each award 1 to 3 stars, and it runs in landscape and portrait on desktop and mobile. Boss fights arrive on levels 8, 12 and 16: Big Puffball, Shelf Cap and Spore Mother, each attacking your heat instead of your health. Between battles you can spend coins in the cafe on perks, claim a daily reward and chase achievements.

Only the cats standing on the wall can shoot the Mildews marching toward your gate. Every shot heats a cat up; when its burn time runs out it jams and stops firing until it cools. Drag hot cats down to the spawn zone to cool off, then send fresh ones up. Drop two matching cats together to merge them into a stronger tier, and the merged cat starts completely cool, so a merge is both an upgrade and a rescue.
