Holy crap I was clicking and exiting so fast once I got it lol
The idea is great and the old desktop interface you made looks so nice! Especially that CRT filter. Like others have said, just needs a difficulty curve. If this was expanded I think it would be awesome for your boss to bash in if you pick something bad for particularly important emails. Would make it even more stressful ;D
I like that you have to have to maneuver in 3D to grab the coffee and then back to 2D. Definitely would be hard for someone newer to games but for me it was really engaging. Good stuff!
