Cool! Nice and short. Definitely a good start. I like how you have to consciously think about the emails you get and decide how to deal with them. I do think the gameplay gets pretty repetitive so it could be cool after the jam to add some additional gameplay. (could be a really cool mobile game where your in an office trying to manage everything!)
Some things to consider:
- Putting normal emails into the trash doesn't seem to have a penalty other than not scoring so it could be cool to lower the score if you put a good email in the trash.
- Spam emails tend to spawn on top of other emails which can be a little weird
The idea is cool so some more polish and gameplay and this could become a really fun time waster!
