Hello @Kyriegabas I am not surprised to see your post in the mechanism thread… This afternoon, I happened to « open » your level in mekostudio 3d builder because I wanted to see the inside. The mech is very interesting ! It made me look for some more infos on the web about locks and especially big safes. Is it a hobby you have or your job ? A big yes from me. But I think your level has two defaults. The first is not that important - because of your separate post - but it explains the lack of comments, I think : as everything is hidden, the level is impossible. Hints or not. It’s only my opinion but even without the walls I had some difficulty to win. And some difficulty to understand the hints (not clear) 2nd default Spoiler the wheels are not stable, especially the last one which makes the whole thing even more difficult. I hope it can be fixed because the idea is great. Thanks for sharing … the game and the inside
