Hi the current version doesn’t have a quest log or in-game hints yet, so it’s easy to miss scenes or wonder how to progress. I’m planning to improve that in future updates by adding more interactive dialogue options and possibly a system to guide players a bit better.
As for the characters, there’s more coming soon. Bulma will have new content and specific scenes in the next update, with more interactions available. Videl’s story is still at the beginning, but she’ll get new scenes and animated content too in the v0.50. Bulma’s mother and yellow-haired Launch will have also with new animated scenes, including dominant Chichi. Android 18 will be properly introduced in the update after the next one, along with Krillin and more locations being added to the map. I appreciate the feedback, it helps me improve the game and make it more enjoyable for everyone.
