Awesome! An RTS-like in Phaser. Maybe I'll give a try to this genre as well in the future. Multiple unit control and more levels is what I really would like to see. Anyways, you nailed the theme. High five for the 12 monkeys reference. And I like the graphics and sounds too. Are they your work, or some downloadable assets?
