A fine game. I enjoyed the concept of using the tentacles as platforms after making them disappear. I had some pleasant "Ah-ha!" moments. I wasn't able to understand the riddle the elder gave and therefore could not progress (that just might be me). Using A/D and space has movement and using the mouse was a bit tricky. I would liked to see more of the game but I the point I reached had me stuck and I couldn't find a way to progress in the elder's room or the one before it. Perhaps this difficulty was intended. For me I wanted to keep platforming and not think about the riddle.
