This was great! The reverse city builder concept is a neat take on the theme, and the levels felt nicely challenging.
The fact that you squeezed in a little story is really impressive, although I have to say, this feels much more like Thor than Odin.
I was a little disappointed when I realised I could only use lightning on some buildings. It would be cool if you had more flexibility in how you used your powers.
Overall, I really enjoyed this one, and I'd love to see you develop it further.
