About Elise is now being delayed and 2017 is the new scheduled date for its release. The interaction with puzzles has been created from scratch in order to make it as best as possible. This means most of the areas are being created over again too so they can fit with these new changes. I can't give you an exact date, but expect it to be released in the first half of next year.
There will be changes in the gameplay in order to improve the experience without changing the original ideas. This is a direct way to answer the testers' feedback. For example, players will still have to read notes in most puzzles, but in a different way. In the earlier builds, the player had to click an object to interact with it and that loaded a new scene for the object itself. Now, that's been changed and that new scene isn't there anymore for most objects, making the game's weight lighter and creating a much less intrusive experience.
Elements that excessively guided the player have been deleted as well. These elements are the footprints, seen in the first trailers. This was an ability that Owen (the main character) was supposed to have and lose after the second puzzle. By eliminating the footprints, the story changes too, turning more coherent.
Last but not least, I want to apologize and say that I am the sole responsible for this situation. If I have to learn by delaying the game to make it better, this is the best position I could possibly be in, with a project that I started creating so I could learn as much as I can from it. I'm still thankful to those who helped me pass Greenlight like I was on day one.
