As a lo-fi lover, I have to respect the use of lo-fi beats in the game. And the way it is used to balance the otherwise risky nature of stock trading is a good call!
The game itself is quite fun and I like how I have the option to speed up the progress of time in case things are too slow for me. One thing that I think can improve the experience is if there were more visual indications of whether the stock is going down or up from the initial price that I bought it for (E.g. Change color of the text, Using a graph, etc...). But overall, this was still nice to play!
