Game is fine but hiding guarantee or pity behind a paywall is a dick move. There's also no way to increase VIP levels in the long run and the requirements to ascend a character to 6-9 stars is incredibly high that I can actually say that its an option unavailable to 1 week players unless they decide to spend. Also locking stage levels behind user level is also a very big dick move making the game lose actual strategy. All in all its a fine game if you plan to play without actual progress.
