I really like the movement concept! I could imagine a frankenstein-like scenario where you are the heart and slowy build yourself back into a humanesque being (a zombie I guess) by finding your limbs, organs and head, all of which change and extend the movement capabilities provided. And what then? Idk maybe go into another area and attack civilians or something. Maybe it's halloween and no one suspects the horrors that will follow after they innocently open the door for you...
Also just a quick question: How did you create the first part of the level? I tried to redo something similiar myself but it went nowhere... Like, did you create a landscape and then put on the organ-material onto the landscape-mesh?
Anyways I really look forward to further development and if you'd like to develop it further (even after Halloween and not alone anymore) I'd be up for that.
Cheers and really good work so far imo.
