Only one level but a great game! Good work on it, it was done very well and it also looked very good. I liked the concept and also how you could merge the gun types, lol. I was cool to see a contrast in the levels not seeing just the gun level but also the falling level, I also liked how you made it keep going with the boss I guess... Heh.
Anyway, this diserves a great big... 10 out'a 10!
