The visuals look really cool for a jam game, I like the sort of comic-y feel and the colors are nice and soft and comfortable. It works well ith the music, too, even if you didn't make that haha.
In the beginning I didn't know that I was supposed to find the room in the hospital after I arrived. I also didn't know what the bar on the left does with the blue and red and which way it moves and what makes it move. I now think it's a timer, and it symbolizes the organs heating up and unfreezing. Perhaps some explanation or an arrow, or even a timer on top of the bar could help!
I think finding the room could be made easier by a bigger minimap, because even once I understood I had to find a room, it felt like flipping a coin which path to go down, because there's usually only enough time to go down one path, and if the room isn't there, you're out of luck. It might be benficial to add some basis for the player to decide where to go. Maybe the names of different hospital wards, and the player has to remember which organ they have, and then guess which ward is most likely to contain their goal room?
Driving fast was fun, but at some point I noticed that I can't do that because missing the exit basically means losing, and the exit can come very unexpectedly. It creates a nice game flow though of first speeding up super hard and then slowing down and waiting for the exit. Maybe you could announce the exit sooner though that the player can have more fun with fast driving and doesn't have to be nervous all the time :D
