Robot Room is a fun, cute, sometimes baffling room escape game featuring—you guessed it—robots! Don't worry, though, they aren't scary, mean robots a la the Terminator; their sole purpose, it seems, is to stand around with their hands in the air (raising the roof?), tantalizingly dangling important escape items just out of your reach.
There's a fair amount of Japanese text in Robot Room, and at times it can be frustrating to find potentially-helpful notes written in a foreign language. However, despite the language barrier, Robot Room is solvable; more difficult, certainly, than if there was an English translation, but solvable nonetheless. It's a nice room escape with some interesting and quirky puzzles, and you definitely ought to give it a shot.
