Hi! Thanks for playing the game. I am not sure at which part you got stuck, but I can give you a few hints.
SPOILER ALERT:
- The lightning changes the hero's direction away when struck next to him. While the wall only bonks the hero when clicked, but does not change his direction.
- The lightning can be struck on one spot multiple times.
- In many levels, you can use the windmill to make the hero fly (and they can be used again after a cooldown).
- The bananas are annoying intentionally :D
