Sylvania

A zen sliding-block puzzle — one move a turn, then the forest settles.

Sylvania is an endless sliding-block puzzle set in an enchanted forest. Each turn a row spawns at the bottom, you slide exactly one block, and gravity, completed rows and any chain reactions all resolve before the board pushes up. No levels and no clock, a single run that grows steadily heavier, and it remembers where you left off.

Development notes

One-shot in Flutter around a single rule: the engine is a pure function of (state, action) and the animation only narrates it, so every bug reproduces from a seed and a list of moves. Two things the one shot couldn't get right: The turn order — it cleared rows after pushing the board up, so blocks sat outside the board. And the art - two image models missed aspect ratio, stroke width and alpha on every sprite, so the shipped set takes material from them and geometry from a deterministic renderer I could prove.

What's in it

• — One slide per turn, everything else follows from it
• — No timer, no lives, no levels
• — Coins from cleared rows buy power-ups
• — Plays offline; the board remembers where you left off
