Xtreme Ball Adventure is an adventure game , with 60 level , 10 secret levels , 11 balls to play with , 4 General abilities and and over 20 special monster abilities and attacks, a lot of Traps , over 50 Enemies and 20 Boss to defeat , your mission is to collect all SpaceShip parts on your adventure , then you can make the monsters back to there planets , but be careful , that will be not easy
I would say first one cuz on second one colors are a bit too dark.It looks a bit better bumped,like on second part.
The ground as itself could be good if you have a forrest there and plants but your ground has only few objects around soo by doing what you did you highlighted ground too much.(it's like I am in a game and I think about how is this ground long till I reach enemy or some object).
Example(desert and pyramid in it),but you dont have a desert :)
Anyway keep improving.
second
First one.
