一如既往地好玩！倒是有一个小建议：希望每次在点击“完成订单”前仍能看到当前订单的收益是多少。

Fantastic as usual! There is still a piece of advice from me: I still hope to see how much money would I earn for each order before I hit "finish order" button.

还有一个希望，就是希望能否把添加液体的画面做成连续的，也就是说看着油箱里的油“顺滑地涨起来”，而不是像现在这样“一段一段地涨”。不知道这个改动会不会很困难，但我觉得如果能改动这一点，对于游戏体验的提升会是很大的！

And another hope...What if make the animation of adding liquid being "smooth"? Can we see the liquid in the oil tank "climbing smoothly" in the future, but not "climbing fitfully" like right now? I am not sure whether this fix would be very difficult, but I strongly believe if you make this little fix, it would raise the gaming experiences of players very much!
