Rectangularity is a fast paced retro-style 2Darcade game where you are a good rectangle fighting evilrectangles. Fight for your survival wave after wave. It has dualstick action, so you can move and shoot independently. Unlockachievements and compete with your friends on leaderboards!This game is totally free and I wrote it just for fun as a hobby-- so there are no ads, no in-app purchases, no premium items oranything of the kind.I should mention this game is hard. I mean, the first few wavesare kind of easy, but it gets difficult pretty quickly to keepthings interesting. You will need quick reflexes!The graphics are pretty minimalistic. I enjoy the old retropixel based games, so I tried to make it in that style, but usingrectangles.Joystick support: this game supports most Android joysticks withtwo analog sticks.
