Wow, this game got me.
I think the story is a clever twist on the theme, and it being short mean's it wasn't a hassle to get all the endings! I wasn't able to find the second number for the safe, which is a shame because the true ending is really touching! I really like how you show all the items you can interact with in the level, but one thing to improve on I think would be to make it clearer what the effect of each option will be, sometimes it was hard to guess which option is the sabotage. Though since this game is short its not too big of a deal.
This is definitely one for my favorite games list!
