Thanks for checking out the game! I can't make any promises but theoretically we want to have simple RPG mechanics, some sort of skill system and way to improve weapons stats. How that will look exactly is not 100% clear just yet. Primary and secondary goals (side quests) are on the roadmap. I'm not sure how deep we'll go with the non-linear/branching story stuff but we do want to have multiple endings. Really glad you are looking forward to the final game.
