The Nordic Game Jam for 2016 occurred and one entry is a game I saw noted in a new article on Rock Paper Shotgun and which I thought sounded interesting enough to try out. The piece is called, "Succulents," and the concept is simple for this game created in less than 48 hours--you have a little underground garden and you need to water the earth to make plants (which you then keep watered too). It is easy, at least once you realize that to get water you need to click a porthole for the pool to keep refilling, and literally entails nothing more than dropping a bucket in water, holding it over stuff whilst it drips, and repeating.
It is easy, but also fun. There is a zen garden-like quality to simply watering the Earth and then keeping what sprouts hydrated so it doesn't wither. It is by no means something to spend hours upon hours playing, but it is a fun little way to pass some time and relax. You can download it for completely free or chip-in some bucks from your Paypal account to help show the developers their experimental work is appreciated. I would say you should give it a try, which you can do by following this link.
