7-14 was probably the hardest level I've ever played. I built up as much power as possible, created powered-up blasters stored on the eastern plateau, and then slowly claimed the low ground between your starting point and the eastern plateau. Overflow creeper from the west was a problem. I couldn't afford the build time, power cost, or lost reactor for a permanent solution. I would drop powered-up blasters into the creeper to the west when it got bad. It thinned things out and bought me time. Sometimes I could save them; sometimes not. But I had enough spare from my initial build. Monitoring power was tough at the beginning. I kept a few powered-up but disabled blasters in the middle of my active ones. When things got dicey I'd activate them to help out. I couldn't power them all the time. But when my regular blasters ran perilously low on power, they were a nice boost to keep me alive until the next reactor could get built. All in all it was a great level.
The randomness of battle so far outweighs strategy that planning your moves is largely irrelevant. As a result, it's not so much a strategy game as it is a game of pure luck.
The game froze on me as I opened a chest. It told me I found a phial of nectar and that was the last I could get it to do. So I guess the game is still a bit buggy.
I enjoyed the puzzle, but found it *extremely* hard to get the electrical tape to work. I spent half of my time solving hte game just clicking wires to try and get it *just* right.
