The start menu was great! I think active start menus are a really great game feature. The driving was pretty fun too XD if you get going pretty fast the fire engine can start to do a little power slide.
Overall great game loop: drive to the fire, put out the fire. I think it would have been cool to add some overall objective like having to put out the fire in multiple places in a time period or something like that. It didn't feel like something I could fail at, but it was fun to play regardless.
The art style, sound effects, and UI all fit together nicely. I think it has a consistent theme and it's got a fun game loop.
Nice job!
