Great Beta, but
Like the reviews say, It does need some work. Some ideas-
1- move the camera in, just a little bit.
2- work on making some more interesting graphics, and animations ( explosions etc)
3- Gameplay is alright, but it has been done before, but this seems pretty fun.
4- Try adding in some more powerups that make things a lot more interesting
5- Take the HUD and make it less confusing, the less text the better.
6- Story! and Different Levels
I know a lot of these things will be out in the full release, but the game is pretty fun. I'd suggest a "Droid Management Area" where you can customize powerups on your robot. Like Armored Core
Good luck, hope to see it full and complete. If you need help on Graphics or anything, I can probably help yah out.
