I know for sure it doesn't progress while you're logged off, cuz I kill maxed Bee and LightMantis as my Supers, and they kill the bosses in around 2~3 hits when I log on again.
Anyways, hopefully we'll be able to progress while offline later on, cuz as is, I'm barely progressing. -- Reason being webgl doesn't work well w/ my comp, and it crashes if I keep the browser up too long.
A very important point that you absolutely must understand in order to play intelligently: boss drops are not random. At all. At least with the possible exception that if a boss is going to drop a shard, the type of shard it drops might be random.
Each level has 15 opponents: 14 normal and a boss. In most cases, the boss is just a normal boss. There is a small chance that it could be one of three types of special bosses, however. A "ShardKeeper" boss drops a shard, a "Super Boss" drops a heart of eradine, and a "Treasure Whore" drops 20x the normal copper.
All three of the special types of bosses are labeled on their name. A ShardKeeper boss looks like a normal boss other than the name. A Super Boss is bigger, and a Treasure Whore uses a particular graphic rather than just being a random boss.
All three of the special types of bosses are also much stronger than normal. A ShardKeeper boss has perhaps 2x the normal HP. A Super Boss has perhaps 3x or 4x the normal HP, but also gives you double the time to beat it. A Treasure Whore has something like 4x the normal HP and without giving you extra time. I'm not sure of the exact numbers, but they're all much stronger than normal bosses.
This means that if you're barely strong enough to beat a normal boss, and a special boss shows up instead, you're going to fail unless you can burn some skills with long cooldowns to beat the boss. You won't use such skills unless you're sitting there watching it, and idle games aren't meant for you to have to watch them constantly. That means that it's critical to be much stronger than necessary to beat the bosses you're facing, as otherwise, you basically don't get loot. You'll get some copper and that's it.
If you fail against a Treasure Whore, it sends you through to the next level, anyway. If you fail against a ShardKeeper boss, it does not. I haven't watched a failure against a Super Boss, but my guess would be that that also stops you. Treasure Whores are massively stronger than the other types of special bosses, and also give massively less useful loot.
One consequence of this is that, even if you could push through and barely make it to another threshold before rebirthing, you really shouldn't unless the next threshold gets you an extra heart or amrita. You're not going to get any more loot on the way, so you might as well just rebirth. Another consequence is that the coin boosters are far more valuable than they appear at first, as it means you'll level out ahead of the content and be massively stronger than the content so that you can easily clear whatever special bosses show up.
A tip for everyone, if you get a "free spin" wheel ticket from an orb, don't use it right away. Using these resets the countdown for your next free spin to 24 hours! I got another 12 hours added to my countdown and all I got was 1000 gold.
Sounds like you need a better computer? As other poster said, you don't *want* to be advancing offline. Killing shardkeepers and suber bosses is FAR more important than stage progression, which means you need to be overleveled. And the easy way to be overleveled is to periodically farm gold (and not progressing) by closing the game for a while.
I've obtained 19 hearts... I've only rebirthed once.
(And P.S. Been a while since I played them, but I don't remember advancing when when the game wasn't running in either attack on Moe or fap titans, the only other games like this I've played.)
