Completed thomaswasalone.com. It’s a really beautiful game — perfect narrative, perfect gameplay, wonderful voice acting, excellent music.
Most multi-character co-op games simply treat the different characters as providing different abilities, but Thomas Was Alone creates meaningful, believable relationships between them, despite them being non-marked, non-emoting rectangles. I enjoyed it even more than Home Sheep Home (the iOS Shaun the Sheep game), which is saying something (I was in the Game Centre top 5% for HSH2 for quite some time).
Another plus: it can be scaled up to retina-display resolution, making those rectangles extremely crisp despite the subtle tilt placed on every level.
