This was fun! I really like the sound design and apart from emails spawning on top of one another occasionally, it is bug-free! I'd like to see a mobile version, could be a hit :)
Thank you. The bug with the envelope stacking is noted. I will probably fix it post-jam once I have a bit of time.
Also I don't know how to develop for mobile in Unity yet, but I'll see what I can do post-jam...
