"OH BOY!" So cool to see the challenge growing and hear your comments! :); pretty fun to go over the entries and check the takes on the theme.
Also, fun trivia about the sound effects; hadn't thought about a shotgun as a cartridge sound and it does a pretty good job! That reminds me about the sound I used on mine when the game is introduced on the console, I wanted to record it from a Gameboy I still have around, but I couldn't get a clear sound,so at the end I actually used an amplified Floppy disk sound, hahah!
