I am very impressed that you were able to make such a complex and complete game in such a short time. The story hit me in such a way that I had to restart 4 times because of bugs during the game (the cat got stuck or the game crashed). I really wanted to see the end of the game. I loved everything! Mostly the music. This modern half-samba was very good! And the chase music really makes us eager to get away. Just a tip about the sounds: the first Gameboy didn't use samples. Look for GB tone programs to be more like the original. The only question I tell you is: How could the cop arrest the ghost? This made me more curious than the ending.
Congratulations!!!
