Ty for the detailed feedback! I am glad you enjoyed the game 🐭
The crash after opening the door was unexpected. We did not encounter this during testing so I will definitely look into the issue.
You are right about the boots. They do not increase speed but reduce the noise from carrying cookies. The more cookies you carry the more noticeable you are to monsters. I will add a tooltip in the shop to make this clearer.
I appreciate your attention to detail. If you have any more questions or ideas I am always happy to hear them.
P.S. I will definitely check out your game ✨
