Room Delta, sneakily playable as the banner image on Kotorinosu's site or free for iOS and Android, is an escape game with a presentation so sleek, you're almost afraid to get your smudgy fingers all over it. Once you've click the banner to start it up, playing is as simple as clicking around to interact with things, though there's no changing cursor to tell you what is interactive and what isn't. Items in your inventory at the top of the screen can be examined up close by double-clicking them, which may lead you to uncover new things. As you navigate around the room using the arrows at the left and right of the screen, you'll realise that there's a lot more than initially meets the eye, and some of it is more straightforward than the rest. Room Delta strikes a nice balance between needing to bang your inventory against the screen and using your brain to spot clues to solve puzzles in order to progress, with every inch of it as elegant as you'd expect. Room Delta is trickier than it seems at first blush, so fire up your brain and get cracking!
Thanks to William, Questioner, and Iceninexp for sending this one in!
