I really liked this game. In contrast to Lab Escape (which concentrates on a more realistic scenario), the situation in Retro Room is purely contrived; for some reason you can't remember how to leave your own office, and so must figure out codes, collect items, etc in order to open the ubiquitous locked door. The puzzles themselves are nicely modulated to be thought-provoking but not headache-inducing, occasionally challenging but not maddening (I particularly enjoyed one rather creative puzzle involving tetris-like blocks). Pixel-hunting, also, is blessedly absent. A quick note: in order to put objects away after clicking on them, press the space bar.
I do wish that the game had included some sort of music or soundtrack, but the graphics are well-designed and the overall package good enough to overlook such a minor flaw. Indeed, Retro Room is a near-ideal escape for a coffee break: easy enough to be finished quickly, interesting enough to engage (and perhaps revive?) the mind. Enjoy!
