That games goes great with a real NES controller, so you can throw it across the room after dying.

Ultima Runes of Virtue 1 & 2 for the Game Boy. Great action-adventure-puzzle games. But very unforgiving, every dungeon is filled with fatal errors. I couldn’t get to the end when I was young!

I’m with you; I like the Metro style. If you have an Android phone, the Square Home launcher is a great implementation.
