I think the idea is good, puzzle solving/detectives games are great, but they need to be properly guided. I think a little clearer clues would be helpful, I was only able to get until the point where you unlock the shovel but I couldn't figure out what to do with it because the timer would run out, since I unlock the key for it 15 seconds before the timer runs out. I think more time would also be helpful. A more spacious house would be nice as well too, it feels a little claustrophobic in some rooms. Other than that, this is heading towards the right direction.
