Kevin HY Hau - Hello World 👋

Rules: cover every square with rectangles (squares count as rectangles). The smallest patch has 2 squares. Each rectangle has exactly one number in it, and the number is how many squares the rectangle covers. A small outline next to a number tells you the shape: wide ▭, tall ▯ or square □. Drag from one corner to the opposite corner to draw a patch. Drawing over an old patch replaces it. Tap a patch to remove it. Keys: Z undo, H hint, P pause.
