IGEO comes with a simple premise; match shapes together to eliminate them. You win if the only shape remaining is yourself. Every shape has a unique property to them which leads to having to sometimes match shapes in different orders, or even eliminate them from the map entirely. This concept is handled very well, with the exception of the controls. WASD Movement on a diagonal grid always confuses me personally, and it adds an unintended layer of difficulty to an otherwise excellent control scheme; and there is also no undo button. If you make a single mistake at the very end of a level, I hope you’re ready to restart it from the beginning again. Other than that, the game is well made and easy to learn. A great time if you enjoy puzzle games.
