A Koopa’s Revenge is a fan-made platformer that flips the classic Mario formula on its head by letting you play as a Koopa Troopa seeking revenge against the plumber who has stomped on your friends for decades. Instead of rescuing a princess, you are on a rampage through Mushroom Kingdom levels, stomping Toads, dodging familiar hazards, and taking the fight to Mario himself.
The game plays like a classic 2D platformer with tight controls and responsive jumping. You run through colourful levels filled with pipes, blocks, and enemies — but from the villain’s perspective. Power-ups transform you into different Koopa variants with unique abilities, like a winged Koopa that can fly or a spiked version that damages enemies on contact. Each power-up opens new paths through the levels.
The level design pays homage to the original Mario games while adding enough original twists to feel fresh. Secret areas, hidden power-ups, and multiple paths through each stage reward exploration. Boss fights at the end of each world pit you against familiar faces in creative encounters that test your platforming skills and pattern recognition.
