Fun! The graphics and animations are great. Especially the grunts.

Sound effects are also very good, with a mix of the original Robotron effects with new ones that fit perfectly.

I found it frustrating that with arrow keys and WASD control I could not move and shoot diagonally at the same time. What technique do you use for reading keypress?

The game is much to easy. I like it in the original Robotron that the first time you try that game it is game over within a minute, but you really want to have another go, and you continue to play because you want to improve your score. It is ok that the first 5 levels are easy, but then the difficulty should increase much more.

Online highscores are a great feature too! I agree that you should be able to type your name instead of rolling the letters.

Overall: great work
