Great game idea!
The concept is fun but I tried every number I saw (even #5892) on the lock and it still didn't open, I also had to bruteforce the color coded cables because I didn't know where to look for them, I still managed to get to the party in time by giving an 8 dollar tip to Alejandro xD
I found some funny bugs that I guess you'd want to fix if you're going to make this into a full game: you can infinitely click the elevator's roof which makes it go even over the wall
also if you run out of the elevator after clicking the button and before the door closes, you can call the elevator again and this makes for a funny situation where you are stuck inside an elevator but also with the door wide open:
I really liked the fact that you put some tips on the emergency button, smart game design :)
