Blockfall

What it is

Blockfall is a build-and-explore game by SainXin. You first place falling castle blocks, then walk your character into the new space and turn it into rooms, meeting guard fights and dice events along the way. The author says Codex (OpenAI) wrote the code, engineering and asset pipeline scripts, and the art was generated locally with ComfyUI and Stable Diffusion XL base 1.0; the music is waveform audio the author synthesized in code, without AI audio generation.

Who it's for: players who like falling-block placement with a touch of dungeon exploring.

Before you start: it's a free browser game, played with the keyboard on computers and on-screen buttons on phones. The screenshots are in English with small text; the full language list isn't given. The page doesn't say whether scores are saved online or give an age rating.
