Thanks! On the beats not working, i would try putting it on "Easier Mode" and trust your beat instinct more than the animations, especially when the firemen change distance spacing's it can throw you off since the bucket moves at a different speed to make its target on time.
For the full screen, yeah, i see what you mean, it doesn't take up all the real estate it can and remains at its native 1024x768 render size, ill take a look at that.
I appreciate the bug report and the feedback, best of luck in the jam!
