If you're interested what developers have to put up with when trying to promote their game, I've created a reddit thread detailing some shady business that I've not heard about before I experienced it:

Regarding Supraland development, it's going pretty well as you can see if you receive all the new updates. Soon work on Blueville will start. The current Blueville parts are just temporary - they will all be removed completely.
Right now I'm working on the sandbox setting - the game taking place in a sandbox and the characters being cut out of erasers, playing a story thought up by supposedly a kid. There will also be a very brief intro sequence.
