Too bad...
Art and action are great, variety is honorable for a defense game, and the idea of adding "Time Crisis-like" sequences during the boss fights really adds to the overall fun of a playthrough.
However, it seems that the coding part didn't exactly as much efforts. It seems rather odd not to be able to reload at will, since this is a defense shooting game with... guns, which are supposed to be fired really fast against bosses. On a related note, the weapon switch function seems to be broken, as the Space button didn't do anything to help me out during my playthrough (selfish bastard). I think the balancing of weapons should be pointed out too, because nothing seemed to be even remotely useful beside the handgun, up until levels where the latter wasn't enough anymore.
With a few more efforts, this could be a really addictive game ! Keep it up !
