Palms are not destroyed now :(
User prompt
Palms are stuck on the bottom and not destroyed. This is abug with the onFinish. Better please check the y somehow separately.
User prompt
Something is not right: I get at start 10 palms, but they only palms on the right being spawned one at a time and some of them stucking on the bottom.

You are not destroying the palms when reaching the bottom.
User prompt
Please follow this instructions carefully: 1. Initialize PALM_COUNT to 10. 2. Create an array of palms. 3. Start generating palms as times goes by and adding them to the array. 1, 2, 3 ... until 10. 4. Check if a palm has reached the bottom. If so, destory. You will have 9, with a free slot in the palm array again . Generate another one. Add it to the array. 5. And that continuously!

palms = []; ???? You are not generating any palm

I only see 2 palms and they are nos being destroyed when reaching the bottom :(

for (var p = palms.length - 1; p >= 0; p--) { We don't have palms at start! This is not being executed!
User prompt
10240 Generated palm - Are you crazy? Keep an array of max 10 and keep generating them as you destory old ones! Also they are not starting from the center 50% 50% they should !
User prompt
You are not creating the palms anywhere!

Please fix the bug: 'TypeError: Cannot read properties of undefined (reading 'isMoving')' in or related to this line: 'if (!palm.isMoving) {' Line Number: 321

palms.length ??? that is 0 at the start! Use a constant or something?

I can't see the palms
User prompt
What is happening with the palms? THey are stuck on the bottom! No! You spawn 1 palm in the center, goes left ind iagonal. Then you spawn another on the right, goes right on the diagonal. And that continuosly. And everytime a palm reaches the bottom, destroy it with .destroy() method! Keep references of them in an array!

Are you even destroying the palms when they reach the bottom? We need to be performant and reduce memory issue!
