It would be chaotic, but fun to have arriving passengers going left to right and departing passengers right to left... one terrorist is arriving and another is departing! :-)

release the source code?

Thanks Maniac :).
@bacteriaman. I like the idea of a clock, although I want to keep it obligated to arrest a terrorist. The impending explosion increases the pressure, which would fall away if all or most arrests are optional. Departing passengers: awesome idea to increase difficulty at higher levels :)

This is a good game! Its amazing that you can make a unique game like this through out all the other workshop items, good job!

Here's some ideas.

The user is presented with an intelligence report before the start of each level. The report contains information about a number of known terrorists arriving at a particular time. The information is listed on the play screen at the beginning of the level. The level is scored based on the number of arrested terrorists. A bonus could be scored if the group leader is captured.

The level would start with people already on the concourse. A clock on the wall indicates the time. The user would wait for the arrival time and then start to scan the crowd of arriving passengers. Points could be deducted for false arrests.

You could do the same for departing passengers and have them walk in the opposite direction.

Anyway, it's a great concept. Have fun developing it! :-)

Thanks! I did add the notion of levels, between which are small pauses. But more explicit waves can be cool. I have so much more ideas of course ;)

Very interesting and clever game idea. You should expand on the premise. For instance the passengers should come in waves (i.e. arriving and departing flights).
