First off, excellent work for a 4 day jam. There was a lot of depth to the unit system, with all the different... uh... units. I liked the art style, the heartbeat added a sense of tension. The music got a little repetitive towards the end of my play through. I did encounter some bugs, but the dev was around for the playthrough and knows about them. The main I would want to look at is the selection clicking. In a game where it is a case of frantically on units, you really the clicks to not register, or select the wrong thing. Great entry, well done!
