So, I rated 50 games. What can I say?
After playing first few games, I thought that the theme is bad, because there were a lot of games with the same interpretation or without one at all.
But now I can say that I was mistaken. There are games which use the theme nicely. Here are some of them:
(I picked games with little ratings)
Aketa,
a jam entry by chikun Dev Team.

A game about a little girl stuck in a big maze. And the maze is stuck in one screen. But this time Aketa is going to escape! If it’s not enough to make you play this game till the end, there is an ending song!
Cathode Ray,
a compo entry by Figglewatts.

Even wondered how does a computer screen work? This game will tell you! Follow the electron in its epic journey to a computer screen. More specific, to displaying “ENTIRE GAME” on one screen. Got it?
The Broadenlands,
a jam entry by Wolve.

You wanna go adventuring? Instead of going somewhere far away, why don’t you go to your bedroom? It has much more than you think! In fact, this entire game takes place in one bedroom.
Also, why won’t you play my game?
Kaleidoscope,
a compo entry by Me.

Have you ever looked through a kaleidoscope? There are some crazy stuff. Now, put some moving polygons inside it and play it.
