I am not sure if you have been here or not but visit the discord: https://discord.gg/aNWAu4p8kE I am the game dev and if I am not awake at the time you visit, the community there will be glad to help out. The game does not hold hands at all and some puzzles require out-of-the-box thinking. The hint is already there for the safe, Date - Dates is the key. Anyway I hope to see you in the discord.
