The Floorsland is a series of games I started back in 2011, when a YouTube tutorial called How to make a platform game in advance inspired me to build Flash games. Four main games were originally made, followed by remakes. An RPG is being planned.
The plot and backstory of the series is also an open project on Wikia. Anybody may make up characters, locations, and events, which may be included in the games. You can also find more detailed information on the series there.
