I didn't get nearly as far with this as I wanted to, but this is what I got. The concept is there, and it turned out a bit better than I thought it might. Let me know what you think!

The Graycog Robots have polluted the Solarion world. The Solarions are going to fight back, but they are so low on the solar energy they depend on that they only can maintain high activity for 10 seconds max. Not to mention getting hurt by robos! But there are many, so if you manage your forces well, you may just survive!

DIRECTIONS:
Click on a bottom tile to select a Solarion, then click a blue space to place it.
P to Pause.
R to Reset and go back to first wave.

KNOWN ISSUES:
-Text turning orange. This appears to only happen once I publish to the web, so I'm not sure where exactly its coming from.
