Oh man, so many confusing feelings! A lot of hard work and talent were obviously poured into this project! And it is definitely unique and stands out from the crowd.
The first thing that catches the eye is obviously the art. Very nice and atmospheric. However, it was also the major part of my frustrations - it's 'doodly' nature combined with a slideshow esthetic, makes it very hard to get the bearings of your surroundings. It was difficult to imagine the space around me and where to go. I got stuck on the basement part, i found some doors that I couldn't walk through, tried to use the basement key on them a hundred times, to no avail ;C
Another thing that kinda took away the enjoyment was overload of the ambient/creepy sounds, especially in the basement. There were always at least 2 playing at any time, without any connection to things happening on the screen. If you would take them down a couple of notches, they would nicely improve the atmosphere.
But yeah, your imagination runs wild =D This is one of the most original games i tried on this jam so far!
