Awesome Game, keeps you busy for hours.
I love this game. The concept is simple but very well executed. The level of customization is amazing, and the advancement of the cell is very well balanced with the difficulty increase of the levels.
The few criticisms I have:
>After about halfway through the game, the possible upgrades far outpace the available window space displaying them. A separate window that shows all of the upgrades with their numerical bonuses and losses would be appreciated.
>The upgrades were buggy sometimes, not allowing me to add an upgrade that would otherwise fit on a sequence line. I would have to clear the line and rebuild in a different order to get around this.
Overall, amazing game.
