Book of Demons is a Hack & Slash in which YOU decide the length of quests. Wield magic cards instead of weapons and slay the armies of darkness in the dungeons below the Old Cathedral. Save the terror-stricken Paperverse from the clutches of the Archdemon himself!

Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.

A fun ARPG style game, would be more fun if it were easier to avoid enemy projectiles. Otherwise its a fun little game.
纸片人版的暗黑,普通模式很休闲,硬核模式有难度。 成就党想哭,如果不用科技手段,估计至少要120个小时才能全成就。 职业各有特色,通过装备,每个职业都有不同发展方向。 刷传奇卡片很有成就感,刷等级和所有卡片3级有点无聊。
A great take on Diablo. I had some gripes about clicking being used for both movement AND attack, until I realized that WASD worked excellently. Funny, fun, and surprisingly in-depth. It ages great, too.

14 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
14 on sale1 answered “not sold”0 we did not ask
The 1 “not sold” market is read from the Steam price pass of Sep 15: that day the store answered for this game elsewhere and gave no price there. The 14 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.

Simple yet technical and smart! This game is a gem! Very unique style of battle but rewarding. Difficult but worth the run throughs, and lot's of variability, I still haven't unlocked quite a bit and it always enjoyable! Hopefully with updates, more cards etc it will continue to be great!
淘宝买的话不到5元。移动方式很呆,怪物还有碰撞体积,移动上的骚操作基本没有。如果是喜欢卡牌的推介,喜欢刷刷刷地下城的,不推介。玩起来还行。
es ist Gelungen macht zwischendurch immer mal wieder Spaß und es fällt immer schwer sich wieder zu lösen wenn man erst einmal drinnen ist.

really fun game, chat integration on twitch, tons of achievements
This is a Diablo ripoff with only a couple of differentiators, abilities on cards, open world has been switched with an on-rails level design as you hop along preset paths instead of being able to wander around, and a kind of ugly folded-card art style instead of the fun gritty fantasy art style presented to us from Diablo. I guess one of the first rules of game design was ignored here, if you want to rip off something, you have to exceed the game you're ripping off, or you fail immediately. Here, these guys set out to rip off Diablo, intentionally making a game that's objectively worse. Why is bouncing along a fixed dungeon path better than open world design? Couldn't they afford enough artists to do proper walking animations? You can get Diablo for less than this and it's a better game. If you want a different ARPG, try Torchlight or something else. Don't bother with this inferior and unimaginative ripoff. Also, this is not worth close to the AAA pricing they're delusionally charging for this bundlemeat.
I do like the concept of this game and it is cheap enough for me to recommend. However, i cant help but feel a little dissapointed that this game is so 1 note. Things dont really change through the game and there isnt very much option to shake the gameplay up in anyway. It really does boil down to holding left click over the monster until there are no monsters left. This game is a not difficult, and offers little in way of customization. It plays wells but thats not very suprising considering the art style being what it is. I feel like they could make a sequel into more of a traditional game and less of a 1 note homage to diablo with some pretty cringey attempts at comedy and a musical number to wrap up the end of the game.
