UX is probably the most important thing about designing apps and especially games. By now, every single developer should have realized this. This makes it all the more baffling, to see such huge UX design flaws in fallout shelter. I thought I'd make a shortlist of the most annoying issues I have:

• selecting a dweller vs. selecting a room vs. scrolling:
  
  It seems like every time I want to drag and drop a dweller from one room to another, I have to try 5 times and hold for 5 seconds before i can actually select or drag them. When I want to tap a room or just move/scroll around the map however, all I seem to achieve is selecting dwellers and shooting them all around the place at light speed. There just has to be a better solution than that! How about a toggle so you can only select one or the other at any given time?


• selecting dwellers during battle:
  
  Ok, whose idea was it to make dwellers run around like headless chicken and stand on top of each other as soon as any attackers enter a room? There's a special place in hell reserved just for you. Why can't you implement a pop-up menu for rooms through wich we can select dwellers and apply stim pacs as necessary?


• the objective pop-up is already annoying enough, constantly blocking the screen as soon as there is an active objective like "gather x amount of food". But even worse, the thing is actually blocking other parts of the interface and there is no option to close/discard the message. If there is a failsafe way to piss off players, it's by having a useless popup block parts of the user interface.

that's by no means a conclusive list, but fixing these issues would go a long way to improve the overall game play.

Adding "sudden & random loss of health bars" which I experience regularly increases the frustration even more.

I feel you!

What about suddenly one person's health bar and name overlapping being stuck on screen permanently at every zoom level? It's visually jarring, especially when it's unnecessary.

I can fix this on android returning to the main menu and reentering the vault. I regularly do this to prevent this disturbance during attacks.

Still only a workaround for something that was already bothering people on the initial iOS-version...

Not surprising seeing as how often you actually see them fix non-game breaking bugs in their other products. I can't help but feel that this was released "as is"

Some of these are bad design decisions, some are just bugs. Either way, they add up to a frustrating play experience at times.

The rush button covered by onjective pop up is the stupidest decision

+1, incredibly annoying when you are in a rush!
