Level 10 is the first hard level but it is possible. Get in one of the magnification rings and shoot from there. Concentrate on killing one sphere before going onto another.
I like the vocalization in the game. I think this is the first 5/5 I have given.
Good for a beta. 4/5 (9/10)
For the future version put in the ability to change what % of nanos you want to send. Google Galcon for an example of this game in space (in case you haven't seen it yet).
Good game. What could be improved:1) Exit doors, 2) player and enemy graphics, 3) AI path finding and sight, 4) more weapons, 5) different enemy types, 6) more variety to the environment
In response to foley_800's comments. The game states that it is (Much) inspired by "Moai no su". I have played Moai and find that they are similar but two different games- not a copy. I rate it 4/5.
