Yes, like in your game I first had to integrate and adjust all the systems I needed (dialogues, notes, books, portal travel, minimap, compass, the crystal etc.) and building the world base before I could fill the levels with content. I was working on scripts which would help here but was unable to complete them because of bugfixing the other systems. In my tests I had fun though by looking for the next gate and fighting monsters alone. But after the rating phase the development will continue with more content.
A crash did never happen in my tests so I don't know what I could improve in this matter.
Thank you for playing!
