This was a pretty creative game! The concept is pretty simple but really difficult to master. It did take me a hot sec to understand what I needed to do, even with the description, so I think a tutorial would've gone a long way. Also, I think the game is just a bit too random - while there's definitely the makings of strategy here, because the die changes so fast, you're basically gambling as to what number you'll get whether you're picking add or multiply mode - I think making the die a bit less random, like perhaps making the die 3D and roll realistically so the player can kind of try to time where it's going to land, would improve the mechanic. Additionally, would be cool to have some way to get the rage meter back down (such as if you get multiple on time notifications in a row or one full screen of on time notifications, something like that), and it might've been good to give some leeway for how on time a notification can be, like 1-2 mins (because let's be real, that's how on time our notifications are IRL too sometimes). Great job making this really unique concept!
