The game still needs a lot of work but it has a great direction to follow.
Besides the bugs, the game needs more rebalencing, for the first 10 or more encounter i had where Wurmples. It also didn't help that every 3 steps i took in the grass it started a battle.
Also the 3rd magma guy had a Numel, and starting with a Treecko i through i was doomed, but the trainer's AI was very dumb and only used ember once on my Wurmple.
In conclusion: Rebalence rate of the pokemons, make the AI make better decisions and fix the bugs.
