Fixel
Fixel is a puzzle game made by Martin Magni. It consists of a pixel art of an object or a structure (e.g. an orange) that has to be filled perfectly with a few given pieces that interlock into the pixel art through their holes in order to win.
How to Play
Drag and drop pieces to the pegboard such that the correct colors are filled in.
Additional controls: you can use two fingers to zoom in and out, and pan the whole level.
