Visuals:
1 ... I love thing publish page bg animation -> elements fits together very well.
2 ... LV 1 before going to elevator -> colors adjustment (walls & floors looks almost the same)
2.1 . Character colors are almost the same as bg & walls -> hard too see
3 ... This elevator scene with little tunning (animation would look much better -> example: little samera movement of elevator)
4 ... I am not sure but are those messages scripted to appear after 3sec?
Design:
1 ... Giving player option to disable phone & decide when to send message -> gives the feeling of control.
..... Now I am not able to turn off phone when I want.
1.1 . but this phone message with elevator looks interesting
2 ... I would rather see I am able to spam answers than wait (2sec) if I fail
3 ... what if I fail this puzzle? -> its
4 ... color puzzle would make people give up (is this LV 2 Power Ranger riddle)?
Bug:
1 ... spamming E on closed elevator stacks messages "cant open"
2 ... Looks like you have trigger on test: click test -> exit -> you can not reopen test except going out of trigger range & re-enter.
3 ... writing correct answer -> you are able to enter another answer -> you get message wrong (correct answer still applies)
Sound:
1 ...I can listen this sound more than 5mins good job
