I'm gonna be quite blunt about this. The Beta is way to hard. Evolved Pokemon in the wild before the first gym is insane. Not to mention there's more than one species of evolved Pokemon. Aside from things like Metapod, Kakuna, Silcoon, and Cascoon, Evolved Pokemon in the wild is a really bad idea before the first gym. Higher level first stage Pokemon work, but things like Level 19 Nidorina, Nidorino, and Staravia are just plain insane. Not to mention the appearance of Pokemon happens way too often. Walk one step, a Pokemon appears. Walk another two, another Pokemon appears. It's really too often. The fact that there's such a huge distance to cover before the second town is just insane. Having the healing spots in such locations where you need to backtrack a lot to get to them is ridiculous. Not to mention you have very few Potions available. Sorry if you're taking this the wrong way, because I don't intend to hurt you, but these things I've just mentioned are flaws that will make many players less than satisfied with your hack.
That said, the storyline is definitely quite interesting, and the free Dratini in the beginning is definitely pretty cool. I do like this hack, but it's just those certain things that are getting to me. I hope you understand where I'm coming from with this.
