I agree with the cozy, not so much with the relaxing, haha you need to focus a lot to avoid waking up!
This is a perfect example on how you can take a simple mechanic, and make a brilliant game. I'm pretty sure you took most of the 48 hours setting the tone and preparing the atmosphere. You can tell you work was worth it. Really a solid entry and original on its very own way. I congratulate you and hope you can make more games like this!
