Hot Barrel Cats

Hot Barrel Cats is a feline tower-defense game built around an overheating mechanic. A fungal army called the Mildews marches down the road toward your gate, and only the cats assigned to the wall may open fire. Each shot increases a cat's heat; when its burn timer runs out, it seizes up and cannot fire again until it has cooled. Drag overheated cats to the spawn zone to cool them, send fresh cats to the wall, and drop two matching cats together to merge them into a higher tier. A merged cat begins fully cooled, making every merge both an upgrade and a rescue. Game details: single-player, 16 handcrafted levels rated 1–3 stars, landscape and portrait modes, desktop and mobile. Levels: boss encounters at levels 8, 12, and 16—Big Puffball, Shelf Cap, and Spore Mother—each testing your heat management rather than your health. Characters: 15 tiers of barrel-wielding cats against 5 types of Mildew. Between battles, spend coins in the cafe on perks, collect a daily reward, and pursue achievements.
