Art style is great, but the puzzles are far too confusing. In the first room alone there are (from what I've found so far) three sets of two numbers, and two sets of two numbers (plus the 4 digit year) in the second room. I've used every single combination of those numbers into the 4 digit safe to no success. Normally when it comes to puzzle games, I assume I'm just missing something if I can't figure it out. There needs to be more of an indication of what numbers go where.
