>When I die, I go back to a save point, meaning I keep my stuff but lose some experience unless I go to where I died to get it?

You only lose the currency you had on you while you died, and you can reclaim it. Levels or equipment aren't lost

>I don't have a lot of time to constantly get good at games, but since it is single player, does that mean I can still enjoy it?

Absolutely, there are many features that help you in single player such as summons, plus most enemies, including bosses are very weak to one or two specific things that basically trivialize said enemies. For example some enemy can be very annoying and difficult to fight, but if you use any kind of Fire damage they'll get stunned for long enough for you to kill them. Some enemies take huge amount of damage from holy attacks, some are difficult with melee but trivial with ranged attacks. You get the idea, it's very RPGish.

Overall the game isn't difficult because it requires huge amount of skill or anything, it's difficult because many people get angry if they die and start making stupid mistakes, learning nothing in process. If you have the right mindset you'll realize the game is very beatable.
