Toya Room 2
Toya Room 2 is the quintessential example of why I really, really wish I could read Japanese.
Ah, what a beautiful game. And so intriguing! From the first glance onwards, one cannot help but be drawn into the game's vibrant environment. Or, rather, environments—the game really ought to called Toya Rooms. The player starts in the present day, but with a push of a button can be transported into the same room some indeterminable span of time into the past; press another button and the operation is reversed. Two separate, subtly different rooms to zoom between, each one affecting the other... interesting, no?
At least, that's what I think is going on. As you might have surmised from my first comment, the game is entirely in Japanese, and is quite text-heavy; it's equally possible, then, that I have the situation entirely backwards. Whatever the case may be, it seems clear that the game's major goal is to somehow help the odd creature that lies, barely conscious, on the floor of one of the rooms; you'll need to collect items from both time periods to save him/her/it. To be honest, though, you probably won't find this to be too difficult of a task.
Toya Room 2 is beautifully atmospheric, creative, entertaining... there's a lot here to love. Furthermore, I suspect that there's a great story going on; unfortunately, due to the language barrier many players won't be able to follow along. Maddening! The game is also disappointingly short, only containing three real puzzles, and ends with surprising abruptness. On the upside, its relative easiness means that those who cannot read the text will nonetheless be able to successfully complete the game. For a coffee break or brief pause between classes, Toya Room 2 could be just about perfect—a beautiful bite-sized morsel of escapey goodness to tide you through the day.
