Thanks for the feedback! This helps us to improve our game!
The original idea of gaining and losing money is actually not like that. We wanted cash to be exactly like other items that cost players' money. But after many tests, we found out letting players do the math might not be clever. So we came up with this idea eventually and got not much time left. We definitely gonna think about how can we improve the clarity of all the cards and icons in the future.
For the resolution, I didn't know why I always get a weird resolution problem when uploading games on itch. It always provides different results on different devices. I actually set a fixed resolution which is 1920*1080, but it barely fits on your 4k screen! So I did my research and I changed the embed options on itch. I'm now using "Click to launch in full screen" instead of "Embed in page", and I believe now it suits well in any browser.
However, there is still a display issue. Sprites are losing details when scaling down the browser, but all of them will be solved in the future post-jam version!
