A really nice submission! I enjoyed playing the game though I got very dizzy because of the screen-shake of the shotgun. I wonder if this game is inspired by Vlambeer's games. :)
It's very hard to get to the upper platform. When the flood started, I just couldn't get up and get killed every time. I still don't know what will happen if all the machines are operated though. But nice touch with the warning, it did give me a surprise factor and prompt me to act quicker.
My suggestions for the game, please tone down the screen-shake a bit. And polish on the platforming more.
Seriously though, nice artwork and sound, this is a very polished game for a game jam!
