I do love the art style, but I definitely think the patterns need to be a bit clearer - to be honest I didn't even realize that they were there until I went into the to-do list and saw the note about them (and even then, I was confused about what smiley faces it was referring to ). I also don't really understand the email messages even when trying to use the patterns - no matter what combination I tried, I ended up feeling like it was complete RNG over whether it would be the correct combination or not. I kind of got the impression that the response should be catered to the type of email/sender, but it didn't seem to matter, and a few of the responses available didn't really make sense for the emails. At the end, I was just throwing random responses in and paying more attention to the calls over the emails.
I also think the little easter eggs are super fun and honestly so true to the corporate drone experience (sometimes you really do need a folder of dumb memes to boost your mood to stop yourself from handing in your two weeks), but it would have been nice to have more time to explore them, even if it's a 30 second "coffee break" or something between batches of incoming communications. Right now it kind of feels like there's a ton of extras thrown in but no real reason or incentive to explore them.
