Quite the fun and engaging indie experience - I played this with my partner and caught myself being so engaged at the colorful/bright world. You can tell that the developer put a lot of attention to detail to creating the level and applying a cell shaded effect to enhance it further.
I also loved walking around in between waves and seeing all the cats in the level ( I shall not say more!).
From a gameplay perspective, I started noticing that simply using a base set of skills wouldn't optimize my damage. I had to really try to coordinate with my buddy to use the best set of skills for the wave that was coming up next and swap between other skills for added CC - Whether it was a slow or damage mark to destroy single targets. I absolutely LOVED to work for my successes with my partner.
I would definitely recommend this to folks that want to have a good time with a significant other / friend.
