It's a golf mini-game to deliver dumplings to hungry people. You can choose your own dumplings. It is a 9-hole golf course with a variety of attractive backgrounds. The smooth animations implemented in WebGL and Unity are awesome.
Mailchimp is a marketing tool. Intuit, a global technology platform, said that it will grow into a small and medium-sized business growth platform along with Mailchimp. From a 'marketing' point of view, I think investing in mini-games that are simple to participate in is a good way. Each time you clear a stage, you can play with a new flavor, so enjoy it lightly.
