Killed many hours with Robotron, so why not recreate it with some added game play.
This aplha version is far from being ready, but allows me to play with the gameplay.
All playfields are randomized, working hard on adding more trap doors and floors into the equation, upgrades to your laser gun, bombs and of course many more robots

Here are some screenshots from the alpha version.
