These two screenshots alone, along with the sneaky hints like the hidden character have made me more excited for this game than I was expecting. Not to mention the whole 'connected universe' idea they've got going on.
I'm super excited. I love the rocky cave screenshot, but actually I find the grass in that screenshot and especially the jungle screenshot to be quite dull. It just looks like playdoh slapped down on the terrain. I hope they improve on that aspect of the terrain. I know it's an early build, just thought I'd give a bit of criticism among the hype.
