Thanks for playing. :)
I'll consider adding input mapping in the future.
I'm curious about your experience with the sound. The game has positional audio for most sound effects, and they work well enough using headphones. One of my friends also had a problem with pinpointing the location of the sound, but it turned out that he was using mono instead of stereo.
It's a short game so I tried making it difficult. Hopefully, you'll give it a try again until you find the dog.
