Pages are an awesome adition. Please leave them hard to get as they are the current focus and slowly building things is the best thing in idle/incremental games.
Also another weird thing from game development that i need to say. It's not good to penalize the players with things like decay(It's better to create a mecanic that buffs you early on than one that penalizes you later on.) It's something with loss aversion. When you got a high modifier and that gets taken away from you is much worse than not having it in the first place and gives a feeling of penalizing for being the best player. I understand the mecanic but you should probably 'reword' or remake the way it works into a more positive light. Maybe a % bonus that starts at 100% and goes down as you descend something demonic influence it might seem weird but WoW for example did something similar having instead of penalty when you stay for too long in game a bonus that acumulates when you are offline and then slowly depletes after you log in.
Also this is just a tip don't take me the wrong way you are developing a great game IMO.
Most of the idle games have the same math, your progress slows down and you end up at "Walls" for a long time. If I had increased the health of the corpses, most players won't even noticed. I prefered "penalize" players for maintain balance, but most importantly, I have good plans on Decay state.
Your idea doesn't bad at all. I'll think about it and I'm glad you had fun so far.
I was able to purchase one Tulzscha the green flame when i had 7 soul shards, resulting in me having -18 shards, i really don't know why it happened but the sacrifice button was green when i did. I just wanted to inform you the bug.
It's a bit weird but my minion stats are:
24,12,25,20 rogue
24,10,5,4 hunter
The rogue seems quite a bit stronger than the other one. Is this intended?
Also their names should be indicated as ranger and rogue on their page(This is a sugestion of course)
Hi! Now imagine me, I had to play the whole game more than 70 times before submitting it! And now for each update, more testing gameplays! And I`m still horrible in it! :D
