Thanks a lot for the feedback!
About the menu, I had a different concept initially, but in the end I couldn't get it done in time and ended up going for a panoramic of the level. Optimization was another thing I didn't have much time to do, I know it's in the heavy side overall.
As for the indications, I didn't want to make it "too" obvious, but I agree that I ended up in the other side of the spectrum, making it too obtuse. At the end I was a bit worried that players would get lost, and I think that's happening now. In retrospect, even just adding a few signs showing things like "main door", etc. would have been an improvement.
At the moment I'm thinking about enhancing this game and upload it as a version 2 project (out of the jam). I will add things like navigation indications, a proper dialogue manager component, and a few other things that would improve the experience and make the code cleaner.
Thank you very much for your time and your feedback!
