How to install APK / APKS / OBB file on Android
I heard that the brain train becomes forgetfulness and blurring measures, but it seems to be difficult, I tried but it did not last.
Is there such an experience?
I devised to be able to use it comfortably even for those who are new to 【Forgetfulness · First brain train】 for the first time.
Please give a stimulation to the work of the brain with ease while enjoying a little, idle time etc etc.
