I couldn't figure out where to go while playing but I still had fun throwing glass at scientists as a scummy lab rat. Also the rat hurt sound had me laughing, lol.

Thanks for your time and feedback!
Here's a full guide (SPOILERS):
Pick up a glass shard from the floor, you can use it as a throwable weapon, go to the nearest door from the hallway, clear the engineers, get the frequency number in the back room (and another weapon), get to the left door in the hallway, clear the chemists, find the formula in the back room, get to the rightmost door in the hallway, use the info you learned, get into the rocket, wait, done!
