Chiiiiin (ー_ー)

I encountered a bug where I couldn't level up the weapon shop even when I had enough XP saved up. I struggled by watching tons and tons of ads in a situation where my revenue wasn't increasing at all, but I couldn't make it in time for the hidden quest and it ended... The sense of emptiness is immense (；一_一) I reported it to the developers, but no reply, no improvements. In cases like this, I wish I could get about half of the hidden quest rewards... (ﾉД`)ｼｸｼｸ
