At first, I was quite confused by this game. I thought there was no way to kill the enemies. I don't even know how to fully upgrade. For the most part, it's still a good game. It mostly works because of how unique the design is. I like how it works well in its simplicity.
I just think it has a very good spirit to it. I like how easy it can be. Well, I managed to get two acheivements so it's easy enough. I really don't know what's going on here, but it's pretty good. I just wanted to say that I like this game.
