Built a Stock-Picking game as a summer project after GCSEs

Been building this over the last couple days. The idea: pick a stock, call whether it'll be up or down by market close, and instead of needing to already have friends using the app (like most of these stock-game apps require), you get matched with a random stranger who made a call around the same time. Market closes, you both find out who was right.

Just some hypothetical calls for jokes.

Would love some feedback please from anyone. Also got a link for some more fun investing games ( at least I found them fun - they are also better than this one ).

This is my first post, so genuinely thanks a bunch if anyone actually reads and uses this.
