In the early development stages, the left arm was supposed to serve a part in the gameplay, but it got scraped, and it wasn't high enough of a priority to fix the animation Thank you for playing and for the feedback! I keep seeing you on streams btw :)
Yup, I hang out on a few streams every now and then, it's nice seeing what games are out there and also getting feedback on my own game if I'm lucky. Very lovely community it seems, happy to have joined it!
