Aqua Kitty - Milk Mine Defender

Aqua Kitty is a fast-paced, retro-styled submarine arcade shooter with optional two-player local co-op. You blast through hordes of mechanical sea monsters in your kitty sub to defend the deep-sea milk mining kittens, because the milk must flow.

The premise is gloriously absurd: a sudden shortage of milk forces cats around the world to seek new sources, so your team of milk-mining kittens overcomes a fear of water to drill beneath the ocean seabed and extract vast reserves of naturally forming full-fat milk. Your job is fast submarine action defending them from disruptive mechanical sea creatures.

The game offers branching map progression and three campaign modes: Normal, an Easy version with more health and gentler enemies, and an Arcade survival mode where you collect gems to buy power-ups. A depth-based power-up system gives partial tactical control over what you create and where, a dual-firing submarine carries a rechargeable secondary weapon to manage, and a chain-kill combo system rewards skilled play. It features Steam leaderboards and achievements, hand-drawn pixel art at a crisp 720p, and chiptune music inspired by the C64 and Amiga era. The game was made by a core team of two.
