I really enjoyed the game no real complaints 

Thanks, for the feedback everyone!

I liked your game a lot! I lost on the shield level. I noticed that you could see the grid on the edge sometimes, and spaces that it seems the robot should be able to get through they can't. Maybe make the box collider smaller (I made my own enemies box colliders to big). 

I think that the music was a bit repetitive, you could have changed the loop a little more during the song.

When you die the scientific tells you the story again and if you are not very good at the game you spend more time talking with him than playing.
I want to give you a piece of advice about the graphics because I used to make the same mistake. Make sure that all the pixels have the same size on the screen. You can change the pixels per unit in the sprite inspector so it does it automatically. (you can see the difference in my game https://mestik78.itch.io/empyre , download the first and the last versions).
