Very cute concept and sound effects! I liked that it avoided horror cliches, yet it still felt tense and engrossing because I really didn't want to disturb the poor tired doggies. You have to move slowly and listen, so I really felt like I was walking around on tiptoes.
I tried playing on my phone, and I really like the mechanic of sliding your finger around, but even going extremely slowly, sometimes it was just a tiny distance between hearing nothing, and waking up a dog. Maybe that's unavoidable on a small screen, but if there was some way to make it work it would be a fun and novel way of interacting with a game. Using a keyboard or controller was less frustrating, but not quite as fun.
Anyway, great job on this! I really enjoyed it!
