Bitsy：一个人的小小游戏

Store the whole game as a plain text format listing palettes, 8x8 one-bit tiles, sprites, items and rooms as 16x16 tile grids. Render to a small canvas scaled up with nearest-neighbour filtering. Move the player one tile per key press, block on wall tiles, and trigger dialogue when bumping into a sprite. Typeset dialogue in a pixel font with per-character effects such as wavy or shaky text, and export by inlining the engine and the game text into one HTML file.
