I might skip rating this game unless I missed something, but I tried pressing every key and clicking every button and I can't enter any lab. I might consider playing this game again though, looks interesting.

uh...didnt the game mention that the interaction button is z? try dedicating it to another button in the games settings if it still doesnt work and try again...
if the issue still persisted, answer my comment and tell some more details about the problem and i might be able to fix it!
im so sorry for the inconvenience.
