Shiver by Oxters
Shiver has two game modes. In 'Save Everyone' mode, you have to keep the prisoners from killing each other. Blow the whistle at a point to disperse the prisoners. In 'Survival' mode, you are a prisoner avoiding other prisoners for your own survival. This game was made with the Pixel Vision 8 game engine (and my first time using it!).
Edit: Just saw all the comments, but as @sam-awk said, x is a and c is b. s is start which is used to quit from a game. If you're playing in survival, you move around with the directional buttons. Thanks for playing my game!

My main concern is the abrupt return to the main menu when the game ends, lacking better feedback on what happened and where. Also, it would be nice to see how much time you played or so.
When I hold left mouse button in Save Everyone mode, the game crashes after a few seconds.
Like other folks, I couldn't keep the prisoners alive for more than a few seconds in the first mode and was able to easily stay alive the whole time in the second one. Because of the lack of clarifying animations and the fact that the game instantly resets when you get a game over, I couldn't figure out WHY I kept losing. It seemed like there were still prisoners left alive each time.
That said, this is a cool concept and I think with some tweaks it could work. I'd love to have more ways of influencing prisoner behavior rather that just the whistle.
