For a small little indie game it has a decent amount of unlockable content. It's essentially a wave based survival game with rounds in between that allow you to buy new weapons, passive upgrades etc.

Its got that Rogue-like element to it as every run you'll be offered different items to buy etc.

The problem with this game is that it's just a bit too samey after a while. I couldn't help but think it needs a few more enemy types, a bit of variation in the waves and some more explanation of its core mechanics.

An impressive feat as it stands, but its far from being an amazing game that you must play/own.
