When you think of "the worst NES games" what usually comes to mind?
Silver Surfer?
Dr Jeckle and Mr Hyde?
Action 52?
Yeah, screw all that, THIS is the worst game to ever curse the NES.
Snake Rattle and Roll is a game where you have to slither around eating balls in order to make yourself heavy enough to hit a bell attached to a High Striker in order to open a door to progress to the next stage. There are a couple of stages that don't do this and instead opt for straight platforming challenges and all in all you've got to get through 10 levels of the stuff before you can see the ending.
There are 2 problems with this game, one minor and one major. The minor problem is the perspective. The game has this sort of isometric camera that was probably really cool to see on the NES back in the day but in a game that needs precision platforming, the camera makes it sort of hard to judge where you are in relation to platforms and enemies at certain points. I call this a minor issue though because it's the sort of thing you can just get used to after a short amount of play time. The major issue though is the ice physics, probably the dumbest, most obnoxious ice physics in all of video games and I say this without hyperbole.
The last 2 levels are these icy gauntlets that are full of one hit kill rocks coming at you and the balls you must put in your mouth to reach the end of the stage are flying, so while you're slipping around trying to eat them you're liable to fall of the stage A LOT. The game also has a garbage respawning system so more than once I would die only to respawn off the ledge again and fall right to my death. The big problem though is the ice itself because you never EVER get a break from it pulling you all over the place, meaning that the ice physics are working on your snake EVEN WHEN YOU'RE IN MID-AIR. So if there's a small platform you need to hit, you'll always either undershoot it and slide back down whatever hell mountain you were climbing or you'll over shoot it and fall to an instant death.
The game only has a handful of continues too so if you mess up too often on those ice stages, enjoy being knocked back to stage one every time. Also don't give me any shit about the stage 8 warp because actually hitting that is a pain in the ass as well.
Sometimes playing shit games is fun because having a nice controlled rage at something obviously shit can be cathartic. Sometimes they can be so jank that they sort of come full circle and become weirdly entertaining in their shitness. Snake Rattle and Roll isn't cathartic to yell at and it isn't jank enough to be fun, it's just shit. Shit in it's purest form, unfiltered and untainted by any traces of quality game design, just a massive pile of doo doo.
There is a version on the Mega Drive too but I've not played that, so I dont know if it's any better. But to be honest, after the experience I had with the NES one, that version can suck at a fat one. Don't play this game, it's not good
