Hmm, I'm in two minds about this game.
On one hand, the actual gameplay is really cool with excellent effects, graphics and exciting gameplay. Love to fly around blowing the heck out of stuff and dodging all of the interesting bullet patterns, and its fun to get more and more upgraded. It's just so juicy and explosive! It is a bit annoying to deal with the controls, however, where your mouse can easily leave the screen and cause you to lose control: would really prefer you lock the mouse into the game screen.
On the other hand, the menus and text outside of the gameplay are painfully static and boring in comparison. The text is difficult to read with its odd font and bright highlights on a bright background, and I don't know how to interpret that word dump in the beginning. The ending screen for a level is really dull with just text that isn't stylized in any way to help the results be more readable. The menus and buttons aren't animated in any way, and upgrading is an annoying process where, instead of just clicking on the segment of the bar and seeing it light up, you have to click on the bar, go to another pop-up to confirm the upgrade, and then go back (repeat over and over for multiple upgrades to the same power), and there's no exciting sound or light-up to make you feel like you've gotten more powerful. Would love to see the balance restored between menus and gameplay: both should be exciting to make the experience equally great!
