Side-scrolling shooters, man. I have a complicated relationship with the genre ever since I first played Green Beret on my mate's Commodore 64 around 1988. I still have something approaching PTSD from Super Probotector on the SNES (incidentally, I have played it recently and I'm still awful at it 30 years later). I can still remember the cheat and the theme music from Midnight Resistance on the Amiga.
Mighty Goose was offered to me with a comparison to Metal Slug. Given that was mainly a Neo Geo franchise, I've got less experience with it outside of the arcades, meaning my memories are typically of big, bright sprites rather than the constant dying I probably did. And this game owes a debt to all of the games above (except maybe Probotector, as I actually completed this without crying).
