Game takes too long to get anywhere remotely interesting, the boxes are far too big and it's just not interesting enough. However the biggest issue I see is that you keep suggesting people go to your link that has absolutely no difference.
Hope this helps you target the issue with Factory but I noticed that you cannot upgrade it unless you have the plates prior to it requiring them. It always works after making the plates then resetting and upgrading it. Seems like once it gets a false because insufficient plates it doesn't have a way of checking again until it gets a true.
Some helpful tips. Do not buy Inn or Potions. They are a waste of gems. Don't waste gems on upgrades unless they are at 99999. If you are going to idle to gain coins, it is best to pick a place that you kill enemies in a sec or two as the higher up enemies take too long for their rewards (you also work towards the kill counter achievement faster this way)**I haven't done a lot of testing on this but it seems that gem (blue) chests only spawn if you haven't gotten 10/10 in that area. I have gone back an area to reset my current level at 9/10 and gotten a gem chest again. So it seems possible to farm them that way. For bosses I generally spam heals on my party until I get lucky with a rogue stun then I use abilities and hope the boss doesn't get two big hits in... Sadly even with absurd amounts of health and clicking like a madman it's all up to luck. Doing all these I am now working up to lvl 500.
dbt247 you need to spam heal your party and hope that you get lucky with rogue stuns basically. I was much lower than you are and I managed to get passed it. Right now I am working on floor 300 and my warrior's Health is lvl 286 mage's power is 202 and my heal is 179. Those are the only real stats that matter for surviving aside from maxing rogues stun and speed... In the end it's sadly all luck.
Would be so much better if scarabs were a currency in the level to be spent on skills rather than them being random. Activate them using 1-9 and have them be aimable. No more 2 meteors going off on the far left side of the map for no reason.
This is definitely an awesome game! For those that are still having trouble finishing original mode in under 8 mins heres some tips... 1. evenly space out launchers, saws and proxy mines. 2. don't be afraid to "manual timeout" your beginning combos. 3. Sit back and watch those suckers bounce...
