Being a HUGE fan of Dig Dug, I hate to say this, but in short, I'm really disappointed in this game.
Where to begin? The controls are DOGSHIT, to put it bluntly. In the original Dig Dug (and, to an extent, Dig Dug II), you're IN CONTROL. In other words, when you move your joystick to the left, Dig Dug turns and moves left, right to the right, etc. It's INCREDIBLY counter-intuitive when HOLDING A BUTTON DOWN TO TURN is a quicker way to turn around and shoot an enemy than just moving your joystick to the direction you want to go in. Also, there's NO WEIGHT to ANYTHING. The Pookas are practically FLYING around you as you desperately try to get away with your pathetic Naruto run. It's embarrassing to watch and frustrating to experience.
The GUI is sloppy, but still somewhat serviceable. I can tell what everything is, but it looks very generic and, frankly, pretty unorganized. Drop shadows, or at least strokes, could've made the GUI at least a little more readable.
The character designs and animations are very good. In fact, after playing this game, I would've preferred a character sheet of doodles over this ABSOLUTE CLUNKER. All the other art is pretty bland (at worst), but generally fine. I just don't understand why the characters look very clean and polished, while everything else looks washed-out and low-res. If the game was developed as a singular project and not as a mish-mash of wasted talents thrown at the wall, it wouldn't've looked like the hodge-podged mess I played.
I also liked the music well enough. It's a bit generic, but good for what it was.
I think this game would've played (or at least looked) MUCH better if it had Nitrome-style pixel art and was made in Flash. In my opinion, Unity is better for 3D-oriented games and generally has NO business in many genres of 2D games, especially arcade-style games like this.
Also, It'd be better if the next game was play-tested for QUALITY and NOT marked for release SIMPLY because the protagonist's knockers are big enough. Being a vehicle for something is fine (in this case, this game feels like a vehicle for the Ms. Dig Dug character), but being a vehicle that STINKS isn't.
