The bee's nectar gathering now depends on the current flower nectar level. The return, deposit_nectar, die, and other functions have been updated to return void. Nectar requirements for each game level have been increased tenfold. A new variable 'flower_nectar_level' has been added to manage the amount of nectar in flowers. Also, several functions in GameStateManager were updated to include specific input parameters or return void.
Removed unused code in the bee gathering function, enhancing readability. Also added a new boolean variable 'spawn_snails' in the game state reset function to control snail spawning.
