I find it surprising that no comment mentioned the pokemon battle song being used.
I don't know if you are still working on this game or not but figured I would leave a review anyway.
1. Just like everyone else said, the battle system is a little bland.
2. I felt like it didn't matter whether I won or not in the park due to the payout. $200 for losing vs $250 for winning? Not that big of a difference. It didn't really motivate me to "want" to win.
3. The game overall felt a bit repetitive.
4. I felt like the real goal was to get the most expensive piece when it should have been winning the tournaments.
So here is how I did my rating.
1/1 star: Visuals/graphics
.5/1 star: Audio/music
0/1 star: Gameplay
.5/1 star: Grammar/English
.5/1 star: Taking your players into consideration.
I hope that you continue to improve and look to play more of your games
