I have two things to say in the 20 minutes I've been playing this demo:
1. The game is very delicate. To avoid crashing, I have to let everything load on its own and press the right keys until I actually start playing.
2. This is a question of mine. I understand that the starter Pokémon can be shiny. To find out, is it enough to look at the sprite that appears above the Pokeballs, or do I have to start the battle?
