if i had to complain about somethings :
- the art feels a tad cobbled and a bit inconsistant.
- it is weird that like-colours do damage to each other but at least the way of this is consistent(i.e guns of the players have differing colours from themselves).
- the dash is nice but, it in the easy difficulty, it makes getting to the far corner so your buddy can pick them off very trivial.
- i was a confused for a bit on how to start a new game after winning the easy difficulty as the "thanks for playing" doesn't quite say that its a valid target.
Otherwise i do like the asymmetrical style and friendly fire. the enemies are bare but it covers what one needs to worry about: the quick ones can make more threatening if the bundle up in higher rounds, the slow ones force you to move.
