This is absolutely great news. The developer, Ojiro Fumoto, is one of the nicest people in the business, and also one of the nicest human beings on earth. What’s especially impressive is that he only started learning to develop games around 1 year before Downwell was released (and published by Devolver Digital). A real inspiration to us all. If you want to make games, just work hard and you can do it.
Most of all, Downwell is one of my top 3 game releases of 2015, it is just that good.
