The game I command...
Little Commander
I was looking for a game on 2d strategy, because games like that help to guide me on my X to Y coordination as regards object position and collision in a 2d environment, and I came across Little Commander.
Setup
This game simply consists of defending your rear while planting turrets and mega bomb traps and anti air missiles to ensure that the incoming enemies do not cross your front in which you planted your turrets, flamethrowers etc. the game consists of world war II weaponry, machinery and troops.
Composition
This game has a lot of objects, loops and if-else statements, but everything is simplified to a single environment and this makes it easy to 'compact' and create while animating the graphics concept.
