I found this to be a good game. I do notice that the graphics don't seem to hold up that much. It's still a decent game, because it's fairly easy to understand. I didn't understand how I was not able to pick up the sandwich powerup. I couldn't find anything about that on the instructions. I now realize that you simply have to wait until you lose energy.
I love how the robots died when they were hit by the laser. I was also interested in how good the designs were. You weren't expecting different enemies that weren't robots to show up. The coolest part is probably how you can smash everything. Hammers just make good weapons.
