Thank you for taking your time to play the game and to write this lovely review.
Haven't heard of the Antichamber, but I will definitely be checking it out. Most of the gameplay mechanics for this game were actually inspired by the Hellblade: Senua's Sacrifice.
And yeah - I get what you mean by not feeling rewarded. I will definitely try to work on that in the next iteration! Thank you for pointing that out. :)
