In the middle of the boom of Pokémon Go, a month after it was released, I wrote on Medium a small post with my experience so far.
The battling system is very undeveloped. Tactics are pretty basic: just know the advantages of certain Pokémon types (water vs fire, for example) and quickly tap the screen. The advanced user will know to keep, power up and evolve Pokémon with higher attack power of the primary and secondary attacks. That’s all.
