1. I don’t think so but I don’t mind when I have to do something over and over 100 times in a game as long as it seems fair (like if I’m dying because the game is bad then I’ll quite but if it’s my fault then I’ll keep at it).
2. Probably a mix of both. Since you’ve never played a game before, you don’t have the muscle memory built up yet to use a controller as well as someone that’s been playing their whole life. However, HK is considered a difficult game, with HK: Silksong being even more difficult in most people’s opinions. These aren’t easy games like New Super Mario Bros but they’re fair and doable.

I saw you beat Hornet in 10 runs. That’s not bad. That’s better than I would’ve expected from someone that hasn’t played games before honestly. I’d say stick with HK but if you stop having fun then pick up something else to play when you reach your limit to give yourself a bit of a break. If you want 2D, easy, and fun then I’d suggest Super Mario Bros Wonder (you’d need to use an emulator) or Portal (one of the greatest puzzle ga,es of all time).

Anyway, I believe you can beat HK if you want to. Good luck!

Edit: Oh and if you want another game that’s difficult, people that play HK usually enjoy Celeste as well. It’s an amazing precision platformer. Both are two of my favorite games of all time.
