This is a really fun game to kill some time.

The gameplay is pretty simple:

You control a hero of your choice. You automatically move and have to avoid enemies and obstacles as well as your own companions.
You'll attack enemies automatically once you're within range. The type of attack depends on the hero you chose.

From time to time you'll find more heroes to join your queue, up until you'll have a queue of 6 heros. (Update: You actually get a chance to upgrade this limit)

The enemies get harder the further your get and they start getting good attacks as well, so you have to plan your movement well so you don't touch anything or get hit by their attacks while still getting in a good position for your heroes to attack.

There are powerups that are dropped by enemies and you can upgrade these and your heroes with gems that you find in the game. You can also buy little buffs to help you out.

Overall, this is a really nice game. It's fun, not too hard, and not too complicated. Really good if you have a little time to kill.

Though I think it's better to play this game in small portions, since the gameplay is not that deep, otherwise you might get bored with it.
