“Hello guys we were working on crop farmer but it had to many bugs and we knew we needed to Start a new project! We are trying to make a New one called Blocky World, But we need YOUR help to make this so if you interested in the Game please go to this Link”
…
Just to clarify: You started selling the alpha version of your game Crop Farmer for $8.00 USD - which you are currently still selling. And you admit that the currently unfinished version of Crop Farmer is full of bugs. However, instead of finishing Crop Farmer and offering your customers/supporters continued support for the game they paid for, you are offering a pre-order for a different game that might or might not exist in the future, will likely be at least as buggy, will probably receive no continued support, and, if successful, would only strengthen your believe in this being an acceptable business move in the future.
Did I leave anything out or would you say that about covers it?
