It's fun and I would definitely say it's underrated. Sure it does have a few kinks, there isn't much strategy involved, it's a bit too easy, and I wouldn't say it's the most polished game in the world (it's still early access after all), but it's still quite fun. With lots of different maps (all with different gimmicks to keep the gameplay fresh with every map), abilities, a map editor, a character editor (which gives you lots of options to make a cool character), a nearly fully customizable title screen, and lots of replayablity value. I highly reccomend it!
