In the beta, solar plants don't add anything to your total energy flow. I build maybe 20 of them, and it stayed at +295. The energy popup showed 300 something - NaN. Also, why in the world does solar cost so much to upgrade/build? Wind power produces more, costs less, and works all the time.
Near impossible to place a turret (even excluding the selection bug where it doesn't let you place) near the end, and the energy display doesn't match what you are actually producing/consuming. In the end I was +170, bought 4 more natural gas plants and it still read +170. Thanks to these irritating bugs, great concept but poorly executed.
You can get to level 80+ using only arrow towers and ballistas, just place a row of arrow men at the top and keep upgrading them. A row of ballistas below that, and keep upgrading those. Around level 70-80, start progressively saving more money for interest income, and then buy all lightning towers.
