A new (tiny) IF work -- Key Features! This was commissioned by MakerBot Inc. in honor of their upcoming product announcement, which will be at CES on Monday.
MakerBot is a nifty 3D printer company, and that's what's neat about this game: you can literally print out the feelies as real-life objects as you play! If you have a 3D printer. (If not, you can still look at the model renderings to see what they'd look like. The links will appear as you play.)
You can play Key Features online or download the game file. (Use your browser's "download" option to do that, as the game file may come across as text.)
