Hey, i could not be bothered to manually grind all these achievements so i made a simple python script. I ran it while i went to sleep and woke up to 4081 of the 4096 achievements. I ran it with python 3.9 but other versions may work, you'll also had to install the pynput module. Here is the script:

from pynput.keyboard import Controller, Key
import time

keyboard = Controller()

while True:
# Press and release space - jump
keyboard.press(' ')
keyboard.release(' ')

#wait 1 second
time.sleep(1)

# Press and release 'r' - reset level
keyboard.press('r')
keyboard.release('r')
