Very awesome!
I really liked it!
Music: Epic, in my opinion. Also goes along with what you're doing.
Controls: Nice, I like being lazy and using the mouse ;).
Graphics: Very good, a lot of detail in most objects/organisms.
Bugs: When you get a medal and it saves in your in-game medals but you're not signed in to get it you can't get that achievement again. Unless you clear data I think. If you can't fix that, it's fine but if you can that would be great.
Final note: Very addictive and fun. I love the lightning ability.
