Need some help with game development

I’m a game developer (programmer) and I’m trying to create a simple game, but I can’t think of anything. I’m completely out of ideas. Would love to here some feedback for it. (Btw, these games are smaller projects.)

How about this: a game about an infinite loop of hallways, you could try some simple random generation and add whatever randomness your heart desires.

So like the elevator game but you go in rooms in a hall?

I guess so, it’s really up to you how you interpret it though.
