OK, apparently couldn't resist one more feature in #QRPaint (v0.9.4). Added a Spray tool with a slightly over-engineered random spray and flow rate. 😄 bbbbbr.itch.io/game-boy-qr-... #Gameboy #Megaduck #pixelart #retrogaming

Screenshot of qrpaint in a game boy emulator, there is a drawing of a mountain ridge in black with dithered white highlights on the left side of the peaks and a dithered sky going from top (dark) to bottom (light) and a black moon or sun.

Screenshot of qrpaint in a game boy emulator, there is a drawing showing different sizes and durations of the spray tool with lower and higher densities of random pixels (lighter and darker overall effect).
