I had the same experience as waijee. I tried on pc web browser saw it not clicking and noticed the touch input comment. So I tried on my phone, fed them one popcorn and then nothing happened. I tried throwing popcorn around and they would change appearance, but nothing further progressed. So not sure what's supposed to happen. I do like the art style though and I think doing touch controls is neat but would be good if you had both mouse click and touch! :)
