I got a bug where I lost my staple gun trying to swap it for a tooth. Other than that it worked great! I notice you've said that the game is endless, however I did find a door that had an exit sigh above it but beyond it was more whale insides, so I think there isn't an escape at the moment. I did find another room with a gun though so I was able to get back into the fight. Those enemies are suitably gross as well, it really does evoke the inside of some giant beast.
The visuals and the sounds are fantastic, and they make the environment is gross in a really good way. Lots of juicy squelches haha
Nice entry!
