It's cool to see an arab developer in this jam, I liked that you recorded the audio for the monster that's really cool! The scene before the actual fight with the city that you built, took a lot of space from the game though, I think that's why you're game assets are 1GB, for future games you make you should remove assets from your project that you don't have a use for to optimize your game size. Hope you continue on your game dev journey!
