Motherload is an incredibly addicting game where you control an upgradable drill and try and get as deep as possible. One of the most popular flash games of all time.
Specs
Pros
Pro A few fun puzzle solving elements
Due to the fact that the player can not mine upwards, there needs to always be an avenue of escape to get back above ground. Whether this is leaving enough fuel in order to fly up or leaving dirt laid out in a certain way that the player can climb up.
Pro Random generation allows for lasting gameplay
Each time the game is started new, the dirt that one will be mining in is randomly generated. This allows for a new experience each time played but also a way to make each individuals experience different. This way the game has a longer shelf life thanks to each experience being different from the last.
Cons
Con Short gameplay
Users have reported to being able to beat the game in around an hour. While the random generation allows for some replayability, the time that this game can be beaten means that a single play-though can be finished easily in one sitting. So for those looking for something to sink more time into, may want to look elsewhere.
