Spatial awareness, strategic positioning, problem-solving

geoDefense Swarm is an outstanding game for developing simple analytic skills such as spatial awareness, strategic positioning, best timing, budgeting, problem-solving and more.
Taking game screenshots and then using a photo paint app have increased the learning for me.
The free version is a great introduction to the game.
