In Blockaid by Jayenkai you have to guide a ball to collect the green blocks, whilst avoiding retreading the same path. Floor tiles will slowly reset as you move, but try not to create a blockade along the way. Additionally, there are randomly appearing walls, and spikes, which will attempt to thwart your efforts.
