After a play-test event at our workplace, we decided to re-evaluate our priorities and begin to gradually modify our backlog accordingly.
So I decided to create a new HUD sketch that is an evolution of our previous design.
So there is now a queue that shows context-based notifications (for example, when the player goes to a store or loots money, the queue shows the player's current amount of money)
There is also a time limit / boss life bar that is big enough to be noticed by the player.
