The Reenu subjugate artifact screen looks great. Very colorful and with great visual appeal.

It is a bit difficult to determine when the artifact has been subjugated though. The change in the screen description and the disabled action button work but they aren't a strong visual indicator. I frequently don't realize that the mini game is over.

Possibly the large pulsing network thingy could change color slightly and/or the 6 circular segments change color as well. This would make it quite obvious that the player has won. Or the lightning effect could stop.
