Hey there.
I played the Betas 2.0, 2.1 and 3.0. Let me tell you this game is awesome. I really look forward for this game totally finished.
Btw, while playing I found a couple of bugs with the Dragon Tail move:
1. If you beat a wild Pok?mon with Dragon Tail you won't get exp., like just using Roar.
2. If you beat a Pok?mon in a Trainer Battle the foe's Pok?mon sprite don't disappear, it combinates with the next Pok?mon's or simply stays if it's the last Pok?mon (next to its Trainer's sprite).
That's all, the rest of the game is pretty awesome and I really enjoyed it. Well done!
