I really wanted to like this game. The concept is so interesting, but for me it's way too slow and tedious in the beginning. Things start to get interesting after a couple of prestiges, but some of the stuff would have better to include in the beginning. Autofight needs to move to the next monster from the beginning of the game. Kudos for the very cool concept, it's worth at least one or two prestiges.

After a few more prestiges, I've noticed autofight DOES continue to the other enemies in front of it, but you can change their order so its no big deal.

Something I like about this game is how you aren't forced to kill anything in a specific order. You can just choose an order which works best and stick with it. You can also just skip some enemies that give you stat changes you simply just don't want, which is really nice. Quick tip for anyone reading, auto battle continues fighting the enemy you DIED TO, and once you fully kill off that enemy type, you'll have to turn it back on.

good game, only that they made a grammer mistake "you have killed 1 vampires" its suposed to be 1 vampire

Just found out that negative recovery does not unregenarate

What's the point of quests? I feel like if it's called a quest it should have a reward, but there's no feedback indicating such. So. They're achievements? And not quests? I guess?

Nice and fun game. I really liked how there's a sort of strategy to min-max paths to prestige. There are some enemies you want to prioritize and some enemies you even want to avoid outright. This really came to play during challenges as some enemies that were easy before now become very difficult or even invincible. I also appreciate you making a build export button to share paths. I think it has a lot of potential!
I have a few comments though:
Speed is the core of the game and I appreciate you allowing us to speed up an idle game so quickly, but I almost feel like you max out speed way too fast. After you max out speed, most of the enemies except ones with certain gimmicks cannot compete. As a result, early runs will usually start off super slow then speed its way to prestige extremely quickly. Though to be fair, this is less of a problem later as you kind of want speed to be maxed out as soon as possible anyways (and I also appreciate the speedup button for)
This is a symptom of the previous problem, but I felt that there were some enemies that were just flat out weak for their area. This is more apparent in challenges where it was beneficial for me to choose to fight enemies from the 5th and 6th boss's area before I even fought enemies from the 3rd and 4th boss's area. I think most of these weak enemies fall under the category of new gimmick that isn't just dodge/stun/invincibility or some variation of reflection. However, I think their abilities are interesting and I'd like to see them being more useful. Maybe they'd fit better in a side dungeon you could run. Thankfully, this isn't a problem with the final boss who I can rarely just skip to without decent preparation.
As someone else has mentioned before, you don't really learn about items unless you search for them. Regardless though, most of the items are really nice to have. I'd argue, however, some of the later items are way way stronger than previous items (with the exception of the final item which appears to be incredibly weak). For example, you have items that give 4 dmg, items that give 5 dmg, item that gives 5 dmg and 20 magic, and then you have items that give 50 dmg and 10 fire (which to be fair was the third to last item to be unlocked).
Final comment, which might be a nitpick, but I'd recommend you order the challenges by difficulty. I understand that their ordered alphabetically and where the stats are placed, but challenges are usually ordered by basic difficulty in most games and some might find it confusing when they can't get past a few levels of the first, as the challenges are basically ordered inversely in relation to difficulty. In fact, you really want to complete the second challenge before trying to finish the entirety of the first.

Autofight keeps turning itself off.

For anyone trying to Prestige, it worked after I refreshed once and then clicked "Prestige" instead of continue.

Based on my experience and other people's comments, I'd suggest splitting "Autofight" button into two: one that makes the game restart battle with current opponent after character dies, and the other that makes the game switch to the next opponent after current opponent is defeated (or not selected). I'd use the first one, but not the second (at least, in the early stages of the game I'm currently in).
And please make these buttons persistent, so they don't randomly turn themselves off like it happens with current "Autofight" button.

On a side note: I have an item slot, but how do I get items?
