### 1/5 — 購入したコインが反映されない

*2019-09-16, version 1.3.1*

購入したコインが反映されない事に気付かず¥1000程無駄にしました。面白いゲームだけに残念です。この問題が解決するまでゲーム内課金はやめたほうがいいです。

### 4/5 — Ganz nett, aber viel Werbung...

*2018-03-31*

Einen Stern Abzug wegen der vielen Zwangswerbung, was ich aber bei einem absolut kostenfreien Spiel irgendwo verstehen kann, deswegen auch nur einen weniger - was ich persönlich etwas blöd finde, das man nichts "sparen" kann und jedes neue Level mit einem Minimum an Geld starten muss, auch wenn man dann stärkere Waffen kriegt, dauert's meistens zu lange bis man sie auf Reihe gelevelt hat, um 100% zu schaffen...!!!

Ist ein nettes kleines Klospiel, was man mal zwischendurch zocken kann, komplett kostenlos und durch Werbung finanziert - da auch Entwickler von was leben müssen, nehme ich die in Kauf, aber das mit dem "nichts sparen können", sollte man vielleicht mal überdenken, ansonsten ist dieses Spiel ganz fetzig für zwischendurch...!!! 😊👍
