Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Sep 11 → 0.71/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

作为一款类吸血鬼游戏,原点做出了自己的风格,通过不同“器官”具有不同的连接数以及效果风格,做到了既平衡了强度有做好了新手引导,在类吸血鬼游戏里非常值得推荐体验
10/10 game it is great to just pick up and play and its a bunch of fun thinking up combos for organs i also like that the combos effect you avitar and the avitar of you off spring
ten 10 horas jugado y se me borro todo el progreso que mal esta diseñado el juego
遊戲在一等難度的時候,面對的敵人HP不高,不過當來到二等難度,它們會異常地變得不易消滅,且會出現雙BOSS在一個限制空間裡,先後加入,難怪來到二等才是真正的挑戰。
Pour le coup c'est un jeu très proche de Vampires Survivors... Mais plutôt complexe Basiquement, vous obtenez des améliorations, mais au lieux d'en être juste équipé, vous devez les connecter à votre cerveau en fonction de leur forme pour en bénéficier, et malheureusement, le jeu communique un peu mal ses mécaniques Mais je recommande au moins pour essayer et si vous voulez rembourser avant de toucher les 2 heures allez-y ! Le jeu mérite au moins l'attention !
tremendo rougue like y gratis
definitely more than worthy of its price. I like the theme better than VS but after some time it gets a bit repetitive.
