I loved the atmosphere you created. I also liked the message of the game, especially if it's directed towards a creative dream. I suppose some people's dreams may have less to do with a creative work and instead revolve around things like homework/school/other life things, I think the message of the game still applies though. I also really liked your use of lighting, it all felt very dreamlike and slightly tense, like when we're introduced to Tessellations, the door to progress is sort of hidden from the light, which adds to the feeling like this creature is "hiding" the solution from us.
The creature and environment designs were so imaginative too! I don't know if it's a reference to something but both of the creatures were so fascinating to look at and talk to!
