yooo, that was actually somewhat of a problem in the olden days, so called bodysnatchers that dig up bodies to sell them to universities. I think the idea really suits the theme. The gameplay despite being a bit funny (running speeds are insane lmao) actually works quite well! IT has a high skill ceiling, you actually get a lot better at it the more you play.
I think what this game misses the most is audio, you could give this very cool art so much personality with simple sfx and/or some music!
