Lmao take a while to understand but it was fun. It's little hard to understand what you are supposed to do after removing the case at first I thought I needed to use screws to provide electricity to heart but it was just screwdriver :P. Also it was strange that I wasn't able to break the glass with hammer cuz like common sense duh doy. Concept and art style is cool I like it but still solving the puzzle is lil hard. (I did all the ending btw :P)
