Thanks, glad you liked it!
When the theme was announced, some examples were given that were more or less all "Existing concept, but you play the bad guys". To me, that would not have been very creative, and I really wanted to make something unique where the "reversing roles" part was part of the gameplay, an action happening during the game that challenges something that the player took for granted.
I mean, technically, you could be playing against the best player in the world! =D
But yeah, I wish I had time to code some basic strategies into it, like at least a way to avoid moving its Sun/Moon into a danger tile ^^'
