This looks quite interesting. It's a hack and slash dungeon game which seeks to riff off the original Diablo, but give it a modern spin. It's art style is pretty cool looking, with everything made out of paper. It has your usual hack and slash stuff, but the normal skills system is replaced by a card system where you will be able to build your own deck and evolve it as the game progresses.
They also say that there will be a system running in the background called Flexiscope which will study your performance over time and then be able to create levels as long or as short as you want them to be.
It's due out in the second half of 2016 and is apparently the first of 7 titles in their Return to Games series which aim to take old classics and give them a new spin.
