The only problem I have with this game is that the controls for the turrets aren't explained that well. I had to read one of the other replies to figure out that it is hold to fire. Other than that I really like the concept. I can easily imagine a game not restrained by the 48 hour time limit being expanded to include different turret types, and the ability to swap between different "groups" of constructed turrets. The game is really fun, though pretty difficult. Overall a really cool game, and a great interpretation of the jam theme.
