It's a very good game, although personally it was difficult to play due to my fear of having a job. I found it very entertaining. Including more than one experience minigame was a great decision, since it helps the core mechanic of simply opening cards a lot, preventing it from becoming repetitive too quickly. I found the names of the upgrades and their descriptions pretty funny, the sfx seemed good to me, and the art fits very well with this type of game.
As for some feedback, there is a quite noticeable lack of synchronization between job applications and experience, experience doesn't carry as much relevance as how many applications you have in total, since you always have a lot of experience and few applications. I would strongly recommend lowering how many applications are needed for the upgrades and lowering the amount of experience received.
