This is a personal made game, I did all the programming and made all textures. It won't have amazing game play or some deep thoughts but completeness and a bit of fun. It would be great for me if someone like the game.

4. Use "W" and "S" to control the right scroll bar.
5. Use "E" to return home| anytime.

Game Tips:
1.Make more money in limited days.
2.Item price will only change after one day passed.
3.Each item will have a random top and bottom price cap. These two values won't change in one play through.
4.Hoarding an item will cause its price increase. Notice that events also affect price. So it might not increase.
5.Dumping an item will cause its price decrease. Similarly it's not guaranteed.
6.Lower price is very likely to cause stronger rebound.
7.If not affected by former rules , Price move direction is a 50/50.
8.Higher base price, higher variation. It's all based on percentage.

It's just a mini-game.
