Okay so I played the game a little bit.I played with Dratini as my starter.
Positives:
1)Game Is very difficult in some aspects
2)Good variety of different Pokemon, seems like almost every area has 20+ different kinds.
3)Wild rates on rarer pokemon seem balanced, I caught a Bulbsaur in the first forest and only ran into one once, same with Squirtle in the Pokemon swamp cave.If rare pokemon were that easy to find I wouldn't play, so keep that as uncommon as possible I would say.
4)Story seems to be progressing well, and alot of different characters involved.
5)Some battles require strategy, and nice arrangement of trainers to battle
Negatives:
1)The map is kinda plain in some areas the beginning city and the caves seem to be very blah. I didnt like the caves either, a pokemart in one and a swamp that just looks like dirt, you should change water tiles to a brownish/green color and allow people to walk in it for this area so It feels more real.
2)Dratini as a starter is crazy difficult, I was unable to beat the cave battle to the poke-mart or the teacher until I lvled my dratini to 15 for dragonbreath. Wrap,thunder wave and leer wasn't working to kill them
(It seemed after lvl 15 dratini couldn't lose so all the battles in the forest were cake)
3)The lvling and area seems to be unbalanced, my pokemon was almost lvl 30 before the first gym, I had to lvl dratini to 15 in the first area<--so not sure if thats the reason.I feel the lvls feel kinda generic and it doesnt feel like they are well earned, to easy to lvl, and lvling so fast makes the battles to easy.Seems like most trainers except the bosses are super easy to defeat. In the swamp cave where you get the fossil, you fight team darugas most of them have lvl 14 to 18 lvl pokemon and then you fight the Scientist for the fossil and he's throws lvl 30s.
Basically I would make the lvling more balanced, and the trainers as well.The first battle against your rival was a fun one, I would have lost if i didnt use leer to lower his defense and wrap him to death,Make more battles like that against trainers, if you make it so you have to lvl your pokemon up to lvl 15, make sure the trainers and wild pokemon matchup.I had to lvl Dratini to 15 in the first area but then spent the next hr fighting lvl 4 to 8 wild pokemon and trainer battles with pokemon lvl 10 or under.Your trying to make it difficult but you make it so difficult you have to lvl so high to beat a certain trainer/boss that after you defeat them, all the battles there after are cake until the next boss.
Anyways to summarize it, Your doing a great job and I appreciate the time you spent trying to make this game great.I think your doing well with your story and you provided alot of pokemon to work with. I do however believe you need to map your areas better and look at the lvling scheme, This might be just my opinion but Im just saying what would make the game better for me, and what I think would make it over all greater then what I have experienced so far.Good luck and keep of the good work!
