Before finished looking at it:
The opening is decent, although the robots walking animation should of continued, and when the Electric Robots come on screen, there is a typo error in the text. It said 'Electic Robots'.
The customization is limited, but I should not complain too much, as there is not much in terms of customization you could've done other than the main robots.
After playing about 10-15 minutes:
The game is decent, it's mechanics work.
The upgrade system was decent, although I think you give a few too many upgrades at times.
I had a max level EMP Launcher quite quickly.
Anyway, there was more flaws, such as the camera moving you have to get used to, and there being no full info of your current objective, so at times you may be stuck.
I'd say it had potential, if it's polished more.
May be being generous with 3 stars, but I can't say.
