I really enjoyed the colour palette you chose. I see you've added some feedback questions on your game page, so I'll answer them here :)
1. I read the game page before playing, so I understood the premise before playing. Regardless, I think the game is self-explanatory if the player is curious enough to click around.
2. I really enjoyed the relation between the news headlines and the stock markets and I enjoyed making buying/selling decisions. Though, for me, some rounds seemed hard to play out because sometimes it delt like the headlines didn't directly correlate to how the market fluctuated.
3. I've been going back and forth between suggesting background music. The silence sits well with the situation, but I think BGM would help me settle in the game for longer. I would also consider showing a plus or minus beside each market value so the player knows if the value stayed the same, increased, or decreased like how IRL stocks do.
Overall, I really enjoyed playing and figuring out your game. Thanks for sharing!
