Does bit dungeon ever end?

There is an ending. If you find a white orb at lvl 50+, you get transported to an empty dungeon. There is a boss. After you defeat the boss, you see your wife and you can end the game by walking up to her. Or you can ignore her by going around.

I'm currently at level 167 and finished my second time round (dark world completed twice) and as everybody else says, doesnt look like its ending any time soon, but everything is repeated after the dark world, same bosses etc, but the weapons are slightly more powerful and equal with the enemies

THis is the ending screen of Bit Dungeon 2

There is an ending, same as the pic shown above... If you buy a soul (blue heart thingy) or get it somewhere (after one of the bosses there is a stone crypt thingy that dropped it), you can click on it and it'll take you to another world, after beating the boss there you can join your waifu's spirit

To fight Soul Collector to "finish" the game you have to get a soul. It's on the bottom left. It's a white heart; all you gotta do is click on it. You'll be transported and have to fight the Soul Collector. Otherwise, the game goes on forever. Btw you can get the Soul very early in the game by buying it for 1k Black coins or just randomly finding it. Completed the game on the 27th Room.
