About Last Night (working title) is a game by Bomb Productions Games. Announced in BPG's Spring - Summer 2011 Projects blog, it is expected to release in 2011. It is for the PC and is probably being made using the JIM Engine.
All that is known is that it is set to highly resemble the gameplay of that of The Legend of Princess.
(From the BPG blog:) When a group of four teenagers go to a popular theme park to celebrate their "last hurrah" before graduation, they get more than they bargained for when a mysterious and lovely girl, the government, and the strange and seemingly magic theme park staff begin to interfere and jeapordize their night, their ride home, and even their lives.
