Having played several of the trade card games, I was familiar with the races and ships here, and enjoyed a different take on using the races.
Unfortunately the graphics for each race seem to be mixed up a bit, making it difficult to know which race's ships are on auto, and which ones are not.
More experience is awarded for killing more enemy ships, but aside from the doubling for the win, there is no base destruction reward, making experience for leveling up skills 100% dependent on killing as many enemy ships as possible. This in turn means a "pull your punches" strategy to building up your abilities. The faster and more decisively you beat an enemy, the lower the reward.
The other major problem is the need to click all 8 races and adjust things for each "tab" with the default for each race being the energy level effect "button" that you never need to adjust. This means extra clicking every time you go through all 8 races to pick either the auto upgrade for energy, or to toggle auto-build on or off for the ships. Launching waves with all 8 races is pretty much impossible as a result, as is toggling skills of multiple races as a "set" also out of the question.
Minor bug is that once I had about 3 races' ships unlocked, I stopped seeing any fire from any ships, so that ships simply drift towards each other, then vanish. Bases also stopped firing, but kept killing ships.
Overall, a fun game for an hour or 2, but that's about it. Quickly gets to be too cumbersome and repetative to really be fun, and the controls prevent implementing complex strategies beyond "turn everything to auto and wait."
