Nothing is free. If you get it for free, then someone else is paying for it, that's just how it works.
Also, is the bandwidth really that bad though? I mean, he has to host the site, and the 100meg download, but the servers are run by other people. Plus it'd be easy to mirror the game file to several free file upload sites.
Ok, back to the topic at hand:
Flying aliens: I think a much simpler solution is just to move the advanced dragoon to stage 2, to snipe the jetpackers. But I think a fluttering alien (not FLYING) would be cool. One that has a dragoon-style leap, but once in the air it uses wings to propel itself farther, like a grasshopper. So it wouldn't FLY, it would just maintain its jump for longer.
- Ads IN-GAME? Noooo way. I'll put up with ads on the map loading screen, ads on the score list, but putting ads directly into the game ruins everything.
- I just think the size of the chat "box" should be an option. When there are lots of people talking, everyone's message gets bumped off the screen in as little as 1 second or so. The text should be made much smaller, and we should be able to decide how far down the screen chats can go.
- As mentioned, IRC
- Would be realistic for Bsuits, but unnecessary. Tyrants already DO squash humans, just charge them.
