Hi and welcome to Arcas, a small casual game that I've been working on in my spare time for way too long. The goal of the game is to protect your planet from alien hazards using a defensive arc. I created all the assets, including graphics, music, code and engine.
The game can also directly be played at http://arcas.s3-website-us-east-1.amazonaws.com/
All feedback is more than welcome in the comments.
