Very fun... A couple of suggestions though: I would like mines as a weapon, maybe a machine gun, and fix the glitch when sometimes the game just stops and no more enemies come.
I like the multiplayer function!
Problem is, I don't like clicking dots as my free time. This could be a great multiplayer game if you had something interesting...
Very nice controls and visuals, although I would like to know what I am unlocking. Maybe you could add a little description of each of the dragon colors.
Very original and fun... Many games lack one of these attributes, but yours hit it straight on! My only suggestion would be what was mentioned above; Change GB to GHz, because that confused me at first.
Oh, I remember this game! I played this a while ago, and I think it is very worthy of being on Kongregate. The only problem I see is the speed of the game.
