I think the tendril thing must've been a glitch then, because I did use the purple arms/legs. Also had no idea the game would have an ending, that DEFINITELY wasn't what I was expecting. Who's the real monster...
Anyways, don't worry about going "off-brand", creative projects are supposed to be fun, make what you want to make! Especially because changing the style a bit didn't at all knock your writing off its groove. (Still really looking forward to any horror story games you do decide to make, though...)
