High production values, but some gameplay flaws
I don't like RTS, so I'm upping the score a point to compensate for my bias.
I agree with the previous review that you should be able to build more energy harvesters. Maybe you can later, I don't know... I only played 4 levels.
There needs to be a mini-map! How are you supposed to keep track of all your units without that?
The units' form should follow function, even for the retro pieces. Why is the energy harvester a tetris piece? Why are the smiley's your grunts? Why does the frog repair stuff? Surely you can find classic gaming references that actually relate to the units' in game functions...
The music is kind of annoying, and I hate being harassed to sign up for the contest after every single level... but as a game dev, I understand the latter. Gotta make money somehow, since no one wants to pay directly for a Flash game, no matter how much development time went into it.
