After playing the demo for 59 minutes. I had to quit. I was stun locked in a grass for 12 minutes straight and couldn't continue. Every time I beat/ran from the battle. I pressed right on D-Pad. next battle. Moving left, up and down worked. But right would give me a battle 100% of the time for 12 minutes. There I was battling level 11 pokemons with my 38 Swampert because I could not leave the grass. I was 100% stunned in that grass. All 3 grasses underneath acted the same. Moving to the right will give 100% encounter, making it impossible to continue the game.
