Interesting concept. After the third round the game locked on me in the build screen where you put a piece of equipment on the cell.

I could actually swap between the cells and click on the equipment, but I couldn't return to the screen where you could pick 5 cells to start. There was also a yellow bar in addition to the short red bar I had showing, and it seems like the cells were glowing more that usual. I probably had about 5 cells that I had already created. And I was about level 5. That is what I remember.
