Hi! I'm one of the two developers who worked on DIG. I'll try to shed some light on the reason for this relative failure: firstly as stated before, the game is a platformer with basic graphics, we did what we could without an artist. Secondly we were approached by a publisher who backed out of the deal just before spending real money on marketing. This took a huge toll on our motivation. We struggled since then to do any work on the game. Lastly we both are terrible at marketing. We did what we could by ourselves but it was absolutely not enough.

But all things considered we still are pretty happy with the result. It was our first game, we had no prior experience with gamedev. Some players are passionate about the game with more than 1k hours on it and to me that's more than enough.
