This was a cute game. The controls were a little tough to use especially on level 3 where you start off bouncing around like crazy. I don't mind that the game did not progress when you completed a level, just sent you back to the main menu, but it should have had the next level as the one selected and not reverting the level select back to level 1.
Would have been nice to have a directional indicator to propel the Ecoball, I got stuck a couple of times just bouncing up and down and having to spam the jump to get it to go in a specific direction.
There are good bones here. Overall well done.
