Easy to hard to impossible – Samurai vs Zombies Defense 2 Review

This game was very fun for me and my friends. Sadly as the game progressed it asked me to pay for new levels and upgrade characters that just couldn't complete the stage. Around like stage twenty it gets extremely difficult. Still fun but very hard. There needs to be a better way to get gems in the game without paying for them.
