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.

Ein wirklich großartiges Action-RPG-Hack& Slay-Dungeoncrawler-Deckbuilder..? mit einer guten Portion Humor! Die Grafik ist eine Art "Papieroptik" dadurch wirkt alles wie aus einem Buch, und das hat etwas! Einige Innovative Ideen wie das "Flexiscope" Ein nettes System, welches uns erlaubt die Länge der Runde einzustellen. Mit Zeitangabe, wie lange die Runde dann dauern wird. Definitiv eine Kaufempfehlung für alle die sowas mögen

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.

I finished this 5 years ago when it was in early access. I don't know if they fixed this but what I didn't like was: - a stupid game mechanic messing with your controls - moving the cursor erratically making it difficult to just play the game - some monsters spawning meteors or exploding imps (don't quite recall) from extremely far away and spamming the spawns Overall the game was great, very well designed. Except for that part where your cursor moved on its own randomly, that was just annoying.
Kozacka gra. Gra a'la Diablo czy Torchlight, ale w świecie z papieru :) Jest zarówno tryb relaksu dla casualowych graczy, jak i tryb roguelike dla hardkorowych graczy, więc poziom trudności jest dostosowany pod każdego gracza i jest git :)

This game slaps.
So fun!!!
Want a modern version of Diablo 1 but ♥♥♥♥? This game is for you. Rogue-like in style, with decent yet poor graphics, and cards instead of items for no reason. The full package. And it sucks.
It wasn't an easy decision, but in the end I can't recommend this game. I'd rate it 5 of 10. This game has a lot of pros: great humor, beautiful graphics style (paper) and nice progression system. However, it has one big con, the gameplay. It looks like an action-rpg, but you can only stay in the middle path of the dungeons. So you can only move one dimensional, but the enemies can use two dimenions. This makes it very difficult to dodge missiles. I gave this game an honest attempt, but the clunckiness of the battle system (which is the entire gameplay) is really not enjoyable at the end of the day.
Diabolo on Roids Epik 10/10
