What's a good iOS game for when I need something that's easy to pick up and play during those super short breaks we get at the clinic?

Okay, so I'm usually too tired after a 12-hour shift to deal with complicated games. Tomb of the Mask: Pixel Maze is great because it's simple. You're basically just swiping to move this little dude through a maze, avoiding traps and collecting stuff. It's got that old-school pixel art thing going on, which is kinda nostalgic. I've been playing it for a few weeks now, and it hasn't crashed on me once, which is a HUGE plus when you're relying on it to de-stress during a quick coffee break. It's not gonna win any awards for groundbreaking gameplay, but it's actually reliable and works when you need it. It's perfect for zoning out for a few minutes without needing a ton of brainpower. Seriously, it's a no-fuss approach to mobile gaming, which is exactly what I need after dealing with charting all day!
