I couldn't get past the lock. Only found the screwdriver and the teddy bear, but nothing I tried would work.
It took me a long time to actually see the arrow at the bottom of the screen, to even find those items to begin with, but even with them, I couldn't find what to do to progress further.
Also, some mistranslations from French to English made some sentences hard to understand, or just changed their sense entirely in English (I tested the French version to see what the original text was).
Please let me know how to get past that lock and I'll try the rest of the game, because I feel like I'm missing out on something by just seeing the inside of that chest in this game. :)
