Updating assets and adding level 2

This is update before I am going to sleep on Saturday (08/07/2023 22.30PM Western Indonesia Time). I updated the assets so it became less embarrasing, added static background (credit to Kenney.nl assets). There are still 1 day 1 Hour and 30 minutes left to the game jam, I hope I can finish level 3 and beautifying the game on time.
