DropCore
Rotate. Drop. Chain. Break through.
An endless-descent arcade game with an inverted control: the falling core cannot be steered, so you rotate the whole tower to line up each opening.

What DropCore is
DropCore turns the usual arcade control inside out. The core falls continuously and cannot be steered; instead you drag anywhere to rotate the entire tower around it, lining up each opening before the core arrives. Red striped surfaces are hazards. Accurate drops build chains and charge Core Mode, which smashes straight through weak layers. Endless play sits alongside ten preset stages, an offline daily tower generated from the date, Time Attack, Survival, One Life and a Relaxed mode, with chain medals, cosmetics, lifetime challenges, achievements and records kept on the device. Progress is saved in a versioned, checksummed file with atomic replacement and a backup, and runs checkpoint every ten layers. Version 0.2.0 builds and runs on Windows and Android; hardware acceptance on a physical phone is still to do.

How it is put together
- The tower, interface, sound and effects are created at start-up from bounded generation rules rather than hand-built scenes.
- Progress uses a versioned checksummed envelope, a flushed temporary file, atomic replacement and a backup; runs checkpoint every ten layers.
- A desktop smoke mode renders, simulates and verifies the build with its own isolated save directory.
