PLEASE READ THE EDIT BELOW
Keyboard controls in Module 3 piss me off.
I have no controller that I can use on this game, so I used the keyboard in module 2. Which, although hard to find, were easy to use after very little playing. With Module 3, they made the game much more flashier and amazing, which I enjoy for the most part. However, the new keyboard controls are ridiculous, especially if you played often in Module 2. They migrated the movement keys from WASD to the arrow keys, so now I have to use my left hand for movement instead of shooting, and vice versa. The new shooting controls were swapped entirely, which pisses me off even further.
So, for Module 2, 9/10.
For Module 3, 5/10. Do not recommend the current version. Play module 2 instead if its possible.
EDIT: I apologize, the game elements I had mentioned early have now been fixed. It is now possible to edit your controls in Module 3. Because of this, I give this game 9/10. This is a great game, and definitely deserves more attention than it currently does.
