Why is my game not working?

https://microstudio.io/i/codecat1/gunventure/

Me and another person have looked around for a while now. Is there anything wrong with the code?

when asking for help its better to post this type of link that links to the game page so we can look at the code https://microstudio.dev/i/codecat1/gunventure/

Also could you tell me the problem? As there are no error messages
