Thank you for your comment. Artworks in the game are drawn by our talented artist 1kmountains. :)
At first we planned to add some puzzle and thematic elements, like a energy field that will cause rewind effect on several objects within the field instead of the whole world state. But unfortunately we don't have much free time in the daytime and the rewind system was difficult to stabilize that we spent a lot of time on it :(
Anyway, we appreciate your suggestion. :)
