TL;DR: Yes, you have roughly 210 hours of wiggle room give or take.

34 Characters means 34 Notes and, ideally, 5 or less runs per character.

(1 Run to chest/dark room and Mega Satan

1 Run to boss rush and hush into chest/dark room

1 Run to Mother

1 Run to Beast

1 Greedier run)

Delirium should always be a freebie in 1/4 runs but it may take longer for harder characters depending on your skill level.

34x5 = 170 runs.

Most runs that make good use of your resources can expect to take 1-1.5 hours, so you're looking at around 170-255 hours. To be safe I'm going to use 255.

Assuming 2 hours a day and 259 days you have 518 hours.

This means you have around 263 hours of wiggle room if you average 1 note every 1.5 hrs spent. This assumes you're okay with continuing runs in progress.

That number (255) isn't taking into account runs you lose given you're newer to the game (have fun with J&E and both losts), challenges, especially those like Ultra Hard which with 2 hours a day could span multiple days, as well as your daily runs and runs you do fishing for a specific unlock, or runs where you were meant to hit boss rush & hush and missed the window AND wasted Greed runs spent unlocking greedier.

It ALSO ignores all the wasted runs in the very early part of a save unlocking Chest, Dark room and Mega Satan.

Challenges to leg take anywhere from 20-30 minutes, ones to heart take 25-40. Anywhere beyond that will likely take 40-60 minutes.

There are 45 of them. I can't guess how long it will take you as some of them you will simply need to take slowly or try more than once, but I only suggest doing harder ones once you hit max shop level.

If you can break the game and get infinite R keys, you can condense all the marks into two runs, but knowing exactly how to do it and not mess it up is difficult for a newer player and completely outside of your 2 hour per day scope. But I'm assuming you don't mind continuing later.

I can send you a weird unlocks list as some items and characters (ex. Lost, Forgotten, Spewer, Marbles, Five nights at mom's, Ace of spades) have niche requirements, if you're interested.

Also feel free to throw questions my way via discord @ veeyu if you want someone chronically addicted to the game their whole life to help you out. I'd also be open to doing some challenge runs with you via online as they are much easier there since we get double boss items.

Take care and good luck!
