A launch-and-upgrade game built on repetition, and honest about it. The bunnies are ammunition: you click one to fire it upward, then click again mid-flight for a second boost, collecting money on the way up. That money buys upgrades, the upgrades buy height, and height buys more money — the loop every game of this kind runs on. What keeps it readable is how few decisions there are: two clicks per run and a shop between them, so improvement is obvious rather than hidden in numbers.
