Vectorman, thanks for your feedback! I am glad you're enjoying the game.
I agree 100% absolutely that the boxart and even the game icon matters considerably, and I know that the current artwork, being just a screenshot capture of the game, just doesn't do it. We've heard numerously that people would have passed by the game but only checked it out since they noticed it was from Xona Games, which makes me wonder how many people haven't played the game since they assumed it was a crappy clone of S.I. Our conversion rate (purchases to trials) is insane, and it shows that a good portion of the population who tries the game buys it, which is great, but it may also suggest that there's a ton of other people out there who should be trying it, and a lower, but no 0, percentage of them would buy it.
So thank you very much for your suggestion.
Multiplayer Scoring:
(This should be added to the strategy guide...
)
All enemies and bonuses score the same amount, but they are split among the players according to contribution. If you contribute 50% of the hit points to kill an enemy, you'll get 50% of the enemy's score when it dies. If you kill 75% of the wave of enemies (counted by hitpoints delivered, not number of kills), then you'll get 75% of the wave end and time bonuses for that wave.
The only thing that breaks this mold is when you attempt to pick up an icon that you are maxed out on, you get a certain number of points every frame, and multiple people can extract these points at the same time (i.e. they are not split), since you are each getting an identical bonus for attempting to get an icon you need no more of. By the way, these points are so small, they aren't worth your time, but I figured you should get something for trying to get that last A before you realize you didn't need it.
Note that because waves can be killed faster, you get more points for the time bonus. Twice as fast a kill means 4 times the points. This shared between 2 people means 2x as many points as you would have scored normally. This means you may just get your highest score playing multiplayer. However, when the game gets chaotic in the upper levels, I find that multiple players are quite distracting.
