I thought it was alright, but a bit easy. I found that some levels were WAY more difficult at random intervals.
IMO to do something neat with this go play Red Alert 2 and maybe do something with the prism tower idea: I.E. you light up the nodes to increase power, and try to take out things or something. That makes it actiony and puzzly. Make so you might have to take out things within a time limit, or take out waves of enemies by lining things up.
Who knows? But either way, i'd look for ways to improve on the game aspect.
