Ohh, that makes sense - thank you for explaining things!
Somehow I didn't notice the first time that Hamilton's emojis were different in the two levels, but see that now when checking it out again. In level 1 Hamilton seems happy to see you (although curious what the eye roll and zipped mouth mean, maybe rolling eyes because of the CreatoR's narration and zipping mouth indicating knowledge of the upcoming events). In level 5 Hamilton seems heartbroken, sad, and resentful for what the player is about to do.
I do really love this game's style with all the fun details, like the building dropping in, the dynamic FOV based on movement speed, the delay with "run" before Hamilton abruptly explodes. Enjoy your travels.
