Sheesh, fail... If you need energy, just build the thing and then cram as many solar panels as you can into the remaining space. Problem solved, this game is worse then the prequel.
Lol, there should be high-health "Spammers" hovering in the background, spawining and actually shooting the stuff, and you have to kill them to keep the buildup at bay.
*Needs to be an easier way to get on platforms; I find myself bonking my head on the bottom right before he lasers me.
*Different difficulty levels, maybe? While it seems to be easy enough to get the hard badge for some, I spent about 6 total hours getting the medium badge with 8k frames.
Other than that, awesome mini, 5/5
Hint: Definitely be Chaos Desert, and make sure to completely ignore defensive bolts. Damage, additional bolts, and primary attack bolts are very important- combined with Twice and eventually Combine, this allows you to kill others with pure power, while preventing them from using any abilities with the Special Decreasing spell.
There's a comprehensive game guide (more like encyclopedia, very useful) at the Book of Mages: The Dark Times Walkthrough discussion which is a must-read. (Click the link after the huge text wall, Thanks Silverry!)
If you get as many items and skill points and possible, you should be able to easily win every battle in the game except for when Corruptor first tries to assasinate you. The Chaos Desert orb, which you get from robbing both graves with Sandtracker, is incredibly powerful, as it automatically casts a high and low attack bolt for you free of charge every time you attack.
