I don't think I made it clear but I congratulate you on what you accomplished with the game so far. You've already taken it a long way with all the weapons, interactions, movements, etc. That takes an enormous amount of work and you should be proud of that. Polishing it and straightening out the user experience and progression are minor but incredibly important things which are going to take you that remaining distance to the finish line. The game is already solid in the systems department, you just need to figure out the player experience.
