The jingle sounds like it was made in BeepBox/JummBox. That's not intended to be an insult (at least not for this game, though I use JummBox frequently), I just found it interesting.
It was actually made with LMMS, but I was aiming for a similar kind of retro sound. I've created other music with LMMS though, if you want to check them out: https://soundcloud.com/scorpion-sounds
