Congrats for your submission in due time for the Jam, Yaz!! I was looking forward to play your game in this Sunday afternoon, to enjoy a post-jam rest day and to recover after these exhausting 3 weeks, while at the same time enjoying the all newly created games by the participants! I haven't been disappointed by the world of your game Projet Z. The graphics, story and affinity with the theme are very good. The soundtrack was nice, with a very funny voice acting (well done in 3 weeks to add voice over!).
This game is a "new beginning" to Zork. I found the symbols required by the theme of the Jam, and it's a nice tribute to these 2 games that you loved: Zork Nemesis and The 7th Guest. Well done! Unfortunately for me, I'm not good at solving that kind of logical puzzles, so despite trying my best I found that they were very very veeeeeeery difficult for me! I had to ask for your help, I must admit.
In the end it was way too hard for my limited brain, but nevertheless a very good game for the fans of the genre. You should share it on adventure games forums where passionate players can try to solve it. They will understand exactly what you did here.
You can be proud: good old adventure games continue to survive through you, and this projet Z is a beautiful tribute to them! :)
