Some serious bugs that I spotted:
1) When you lose, the "Game over" screen won't go away if I press "Try again". The game must be restarted afterwards.
2) If you shoot (using the spacebar) while being in the hamster's camera, you can't see the shooting bar.
3) The arrows to switch cameras don't work properly.
I think that especially the 1st bug can be considered game-breaking. Maybe you should contact the jam mods and ask them to allow you to fix it.
