How spicy are Karsu Curry Noodles supposed to be?

I'm not someone with a very high spiciness tolerance but I've been eating more spicy foods over the last two years to gradually adjust to it. I can't do the red Nongshim Shin Ramyun noodles (only half the seasoning packet is my max tolerance) but most low spicy food is now pleasant at least.

I got my first shipment of Curry Noodles and it wasn't until I'd finished one for lunch just now that I realized it didn't taste spicy at all. I read reviews from others who said they didn't like it because it was spicy.

I've had the Mexican chili as well and it's where I'd expect low-medium spiciness to be, but that seems miles away from the Curry Noodles. Now I don't know whether I'll be fine with the maximum spicy H&S meals or whether the Curry Noodles just aren't spicy at all?

What are your experiences with the spicy foods Huel offers?
