Dam it! Beaver on Duty

A combination of a "Papers please" and tower-defense genre. 

The first part plays during the Ebb phase.

In "Dam it! Beaver on Duty" you play as a beaver on a border between two rivers. Your goal is to carefully watch the details of the fish and let them through the border if their details match the ones in the "Match 1 of" panel. 

For each fish that gets accepted correctly, you get 5 coins as your salary suggests, but if you let a fish through that wasn't supposed to go across, you get a penalty, so be careful! 

If your morals permit it, you will get occasional bribes, when declining a fish that wasn't supposed to pass, and if you're careful not to get caught, you will be one rich beaver!

During the Flow phase, all the fish from the Ebb phase that you haven't let through will come back and attempt to cross the border illegally. That's when you need to work overtime and not even be paid for it, as you stop the fish from going with your mighty tail and nets and toads that you hire.

Once you go into -200 debt, you will go to jail and the game is over. Have fun!
