Rectangularity is a free fast-paced 2D retro arcade game where you move and shoot in an arena, defending yourself against wave after wave of enemies. It uses dual-stick control (one finger controls movement, the other controls aim), so you can move and fire freely in independent directions. You can download it on Google Play: https://play.google.com/store/apps/details?id=br.net.btco.pea04 I wrote this game purely as a hobby so there is zero annoyance: it's totally free, there are no ads, no premium stuff, no in-app purchases, no cross-promotion, no nothing. Just pure game. You can unlock achievements and compete with your friends (and the world!). It is also compatible with external joysticks. Most Android-compatible joysticks with two analog sticks should work! I'm totally open to your feedback and I often incorporate feature request into new versions of my games.
