Not bad. The menus are 'fuzzy' and hard to read at times. The only use I found for 'bullet time' was sneaking through waves of bullets to get Powerups and Lives. All in all, it could be a decent game if cleaned up a bit.
Very seldom do I give a 5/5, but this game deserves it. Very well thought out and designed. The racing physics are superb. The 'ghost multiplayer' is the icing on the cake. Very fast paced game play with no lag. This is what other racing games should strive to be better than!
It gets boring a little too quickly. This either needs a better variety of ships or weapon/ship upgrades of some type. And as was said before, the Boss battles are a little too long. Other than that the music is good and the artwork is pretty good too. 3/5
I've added some feedback around a Stall mechanic which I _think_ will help address this for players.
