There are no stairs, bounce your mouse between floors on trampolines to snatch the loot.

How to play
A police mouse works its way through a multi-floor mansion recovering stolen goods, and the house has no stairs. Trampolines are the only way between floors, and they are limited in two separate ways at once — each individual trampoline wears out as you use it, and every trampoline in the building draws from one shared spring reserve.
Trampolines bounce you up or down to the adjacent floor. There is no other way to change level.
A trampoline breaks after four consecutive bounces, dropping you if you are in mid-air when it goes.
Stepping off a trampoline lets it recover, so the wear is on consecutive use rather than total use.
Separately, every bounce in the house spends from a single shared reserve that recharges only while you are not mid-bounce.
Drain that reserve completely and the spring snaps, which is a house-wide problem rather than a local one.

Tips & strategy
Count to three. The fourth consecutive bounce on the same trampoline is the one that breaks it, and breaking it while airborne is how most runs end.
Step off between trips. A moment on solid floor resets that trampoline's wear and lets the shared reserve recharge at the same time.
Treat the shared reserve as the real budget. An individual trampoline breaking is recoverable; the house-wide spring snapping is not.
Plan routes that alternate trampolines rather than hammering one. Two bounces each on two of them costs the same reserve and breaks neither.
Doors are your only defence, so move toward one when cornered rather than away from the cat.
Origins
Trampoline Heist recreates Mappy, released by Namco in 1983, in which a police mouse recovers stolen goods from a house full of cats.
There are no stairs. Floors are joined only by trampolines, and bouncing is uncontrollable once begun — four bounces in one spot and it tears. Your only defence is the doors: opening one in a cat's face stuns it, and a handful of special doors release a wave that clears the whole line. So the game is played by arranging to be somewhere a door will be useful, rather than by avoiding anything directly.
