Thank you for your take on my game! It's really helpful!
And I realized mid making this that some of the puzzle were a little bit too difficult and that probably nobody would see the end of it. I also should have explain hexadecimal in game. The bundle is not really well explained but it helps partially with items transportations but I agree, it's still annoying. And I agree, the game becomes really hard in the second location and the third one (the final boss) is even worse, I don't think anybody will finish it. It becomes really hard and almost impossible even with the help of google or calculator and it really was a mistake. But I was conforted by the idea that for the last puzzle (the hydra's head), I "did" the puzzle on my own while making it, just giving me a result and trying combination to obtain it. And I enjoyed it even if it was really really hard even with all my mind at it for the past week.
