I absolutely agree with you, the energy items being locked behind paywall and the minigame design is flawed. I just never came across it as a problem because I always saved up alot of coins. But the double block thing is pretty unfair, I hope they fix that bug. My biggest issue is still with the lag, but I agree that line breaker can be easily fixed by making a fast and slow lane with fast lane having obstacles. And on the Gravity Rush one, that's fair, I generally just look at ahead and if I'm going to hit a wall, I just left click. But at a certain point I just end up clicking every 1-2 seconds. But everyone probably has a game they struggle with the most. I struggle with the line breaker one the most, I get greedy...
But yeah the difference between f2p and whaling is pretty black and white. Hope they do work towards fixing that. If not, its not like I spent a dime anyways, I can just drop it when I get bored.
Haha I hate that my top 2 includes Raquel... Most of my diamonds went to her xD Anyways I was happy to hear you give the game another chance. Happy Gaming!
