I don’t think I got very far, but I like the concept. Agreed, nice art, nice simple tasks for the work side, agree with those who’d like more than text for the fantasy side eventually. I have a pretty hi-res screen and somehow that (or something) caused the content to be very small and in the upper lefthand corner of the window. Does indeed feel very true to life, and agree too with the comment that you could play up the irony there a lot.

Very nice art style. The only criticism I have is that I think this game would be better with some ambient sound or maybe music playing in the background. 

Sidenote:

The English translation looks good from what I read👍

Interesting game. I think it could go one of two ways.

For a more fun game, action would work better for the fantasy game. Then its like you run around and shoot things and need to find a safe places to respond to emails. Lots of humor on the work side with fuming bosses getting impatient lol.

For a more artsy game, I think there's clear ways the real world sets you up for failure mechanically that could be used. The work could be easy but if you do it promptly, all you get is meaningless praise and more work until it's naturally too much. The fantasy game could have gatcha with a lot of duplicates and grinding mechanics that go nowhere. Maybe even money you get from work you can funnel into the game with no real benefit. What would the ending be? Not sure. Hopefully some sort of realization that without a fun game (or hobbies, dreams, passions), work is meaningless.

 Just some random thoughts. Cool idea!
