To discuss a gameplay idea a bit:
Player needs to dodge falling lawnmowers and avoid colliding with them while they are horizontally driving/mowing.
Next to that, when two lawnmowers collide explosion occurs which can also hurt the player.
As time progress fire in the kingdom, caused by the exploding lawnmowers, is catching more buildings which is shown in the kingdom bar in middle top area of the screen. Buildings in the background will also reflect this progress of the fire with each new segment of the bar being affected by fire.
In order to save the Salad Kingdom from the blazing fire character needs to use his "special surfing power". :D
When character is surfing on the top of the lawnmower he's creating a small waves which fill up the bar on the left side of the screen. Once the water bar is full a splash will extinguish fire in one part of the city.
Goal of the game is to save the kingdom by putting down all the fires, while game is lost when character looses all his hearts or if Salad Kingdom burns down.
Player will have a chance to collect coins which are dropped by destroyed golden lawnmowers, and in between the plays in the store menu he will have a chance to use them to unlock some pickups and powerups. This part of the game is still work in progress.
Check out the video and try to spot all mentioned mechanics. :)
