I enjoyed the aesthetic of the game greatly, and it inspired me to get back into artistic rendering. However, I fear that I may have closed the game too soon: I saw the "For A" and "Thanks for playing", but am afraid that I've missed something beyond the credits. If anyone's actually waited to see, is there anything?

I don't think you missed anything. I let the game end, and the synth music fades out and it stays on the black screen until you close it.

I was sure that I hadn't seen one of the rooms on the pictures on the bed, I was tempted to get back in the chair!
