You are right about the menus. I've considered your feedback and made starting the game easier.
I have thought abut making the camera fixed angle, controlled either by keys or mouse. There are pro's and con's, but as you pointed out it might be necessary.
Sound effects are very much a work in progress. I haven't spent much time on them at all. I'll check the volume and make adjustments.
I'm working on the UI and user feedback to make the game easier to understand visually.
Thanks for your feedback.
