This was a massive game and I commend you for undertaking such a big project for a 10 day jam and you did a really good job with it! I did not make it all the way through (yet) but played till 50% and have pet 1 cat till now haha (even i love cats :)).. The concept is good and full points for theme for sure! Im personally not the biggest fan of FPSs, but the combat in this one was quite forgiving and allowed someone as bad at FPS as me to proceed this far into itwithout getting frustrated. I like that you focused on the ambience and story and adding interesting elements rather than the combat. The world itself was really well designed with so much variety in the buildings roads etc. I was not a big fan of the art.. although i understand that having too many detailed 3d objects for such a large map would have blown the size out of proportion especially a web build, All the features which you implemented including QOL features like map were done well.
One other place i felt which needed a bit of improvement was on the gameplay which felt a bit long and although there was combat periodically, i thought it could have been more compact length wise. Plus i am not a huge fan of this genre, so it wasnt my cup of tea after a certain point. Other than that, i loved the audio and the general ambience of the world you built. Overall really well done :)
