I have released a new version of the game that has redesigned the UI completely from scratch using Bootstrap 4.41. I think it looks much more sleek, and it has given me the chance to address an issue with investments not working in the previous version without having to build on bad code. Please try it and continue with the feedback. I am going to look in to adding more content soon now that i have a good base foundation. Feel free to suggest what that should be, and anything else.
Note: I have made the interface larger and so scrolling is possible depending on your device resolution. This is not designed for mobile and so you will probably have issues if you try.
