I'm impressed. This game is well designed, complicated, and success depends on a number of factors, including: experience in the game, a sense of timing, luck, judgement, ability to learn from mistakes, and, whether or not the player is distracted at the moment. The format is really interesting. The combination of limited slots on the planet, and lack of knowledge on the slots of other planets makes it really fun to try to design your arsenal. You get to feel accomplished when you recognize a counterproductive strategy. I will be playing this one for a while. The update that included the ability to change the game's variables made it more accessible to the general player base by enabling what we used to call "trainers", but also allows for more advanced players to still have fun. I'd honestly have dropped another half star on this, except for one feature I find missing. A "self destruct" button. I know, I could close the browser window, reload the page, select a new campaign. But seriously, that's a lot of clicking and waiting. When I make a bad call. I forget to take actions that will allow me to enter a fight at close to full health, or I just blatantly forget to do upgrades before intentionally picking a fight, please oh please, pretty please with sugar on top, can I have a button to press that says "Blow My Planet Up!"? That would save so much trouble! Again, good game!
