I played the browser version and I acknowledge that there are some missing elements in the web version.
3D graphics are nice and polished, I found it fun that the camera was the actual display of your player in real time as when he speaks I could see some lasting shoot passing by me. Pleasant effect.
I find it frustrating that you can't push the dead robots, you could get stuck easily. It seems that the enemies aren't affected by that though as they can make their way even if a robot is dead.
I liked the wink at star wars with the intro (even though I'm not a star wars fan) but the text that couldn't be skipped on second try was a pain. I know you know it but I still wanted to let you know my thoughts.
The music is a bit out of theme but it was dynamic at least.
The game plays nice but shooting wasn't too much precise. It doesn't aim where your mouse is, You have to be careful when shootings at enemies because you might miss them.
I don't think there is a "next level"? Upon finishing the first one I clicked next level but was brought back to the intro (I guess?)
Anyway well done for your entry :)
