Hi everyone, thanks for all the feedback! We pushed a quick patch to fix the javascript error at the start. Also, at the top of the ladder when movement cuts off, it will resume after the conversation is over, (the game hasn't crashed!)
As for the sound effects, none of us are very experienced with sound, so we ended up not getting it quite right. We lowered some sounds in the patch to make it more reasonable. We will try to do better in our next project. Thank you! :)
Edit: We hear that charging time for the light sensors is a bit too long, we might make it faster in a later patch, thanks for all who let us know.
