I enjoyed playing! The game caught my attention by its first enemy. And then it really drove the point home when I considered the consequences, then messed around in World 5-4 anyway without inspecting everything.
Eventually Yrkkey reached Paradise! Despite all the effort that took and the discoveries I made along the way, I found the end result less gratifying than the one I earned my first time around. Which is completely fair.
Whether by leaving companions behind or by reaching an area unlikely for anyone else to discover, both endings felt a little lonely.
