Coma is a beautiful browser game supposedly made by the developer of the game LIMBO. This game has absolutely stunning graphics, and the music is excellent, contributing to a calm, happy atmosphere (most of the time). The game's story is common among 2D games like this: your sister has been locked up, so you team up with a friend (a bird) to try to save her. But this is no common sidescroller. Your path to reaching your goal is strange, and involves all sorts of. This game therefore requires a little suspension of disbelief, but it is well worth it. This pretty little game will make you smile and absorb you in its frequent cheerful and dark moments. You can play it in your browser here.
Don't look back is a short, pixelated, 2D flash game made by Terry Cavanagh, the developer of the famous indie game VVVVVV. Its graphics are simple but beautiful, and its soundtrack complements the game well. This game is a modern retelling of the myth of Orpheus (or so I read) but it is its own story altogether. While difficult, this game retains a sad, halfhearted atmosphere. Don't let this game's low resolution fool you, though. This game is immersive and will grow on you as you venture further into it. This game is short, but is well worth playing until the end. You can play this game in your browser here or download it for iOS and Android.
