Could be better
The game could be improved a lot.
The art is plainly bad, it's not for the style, but the poorly drawn things make the game look silly.
Also, it's poorly balanced, altough I could purchase most of the goods in two levels or so, there were so many bullets on the screen, plues the coins, that it made it hard to see, also, I would either complete the level or take the coins, the decay should be eliminated imho.
The problem with this is that the enemies are not put in an orderly manner, it's far too random, I don't like it, I think it needs balancing.
