I have played older versions. I was able to get off Rookgaard in a few hours. I even wrote a game guide for tibianews on how to quickly get off and out in the mainland.
Besides, you made an incremental game and people tend to expect quick progression in the genre. Tibia is a slowburn game with high risk, high reward. Incrementals are hardly ever about risk. You will have a hard time finding one that 'punishes' players and taking away progression like Tibia's unforgiving death penalties.
There is another incremental game called Bones Clicker that did an amazing job turning Tibia into an idle game. The progression, exploration, and difficulty was incredibly satisfying.
