Hello guys! I'm from Fireplace, the team behind Oneiros!
I just finished you game... Wow, to think you were only two on this one is amazing! The feeling is really cool (sadly the music may be a bit repetitive). I'd really like to see a full game from it, maybe mixing more the gameplay elements you've set.
Nice polishing by the way, I only noted that, if I use the key on the "machine" when the circle is already turning, this circle will start moving again of a quarter of a circle from its actual position (and the impatient player can end up stucked).
