these were all packages made in 1-2month batches when the game development started to keep people interested/aware of progress and your basic updates to the game, they started as 2-3 days each update. they aren't completely removed sometimes, but Final projects come out as Full Weeklong(7 Days) packages. As a note the Weeklong Packages normally have a bit more content that isn't always shown in the 1-2/3 day files since they are completed works. And just as a note, take anything anyone says with a grain of salt since before 2020 updates and the amount of content made in the time this game started is impressive on it's own, this past year's just fucked over alot of ppl. So just keep an eye out over the next year or so, cus it is a very high potential/ambitious game.
