This is a very simple platformer concept: explore, collect icons that allow you one additional air jump, then reach the area you can only get to once you’ve collected them all.
But, it’s the way it is presented that is absolutely beautiful. The area you explore is blank, but as you move around you sort of slosh watercolour paint everywhere to colour it in. Like, if de Blob and The Unfinished Swan had a 2D platformer baby.
You can wall jump, and slide down walls, and have to get the upgrades in a particular order as each requires one more jump than the previous one. It’s not a long or difficult game, but it is incredibly well put together with slick, responsive controls and a unique aesthetic. Oh, and it’s free!
