Is the Plot interesting?
How can I make the game better?
Is there anything else I should implement in the game?
You could make it better by maybe adding more detail to the plot. Not necessarily more information but a cliffhanger like "But will your intrest in the D.N.A. pokémon draw unwanted attention from team Nucleo?" Although a bit more information would be nice.
Yeah, more minigames besides bike races would be more exciting (although bike races does seem cool and original.
