Hello Friend! I'm the game programmer and first of all thanks for playing our game and giving your feedback, unfortunately here we didn't notice this flaw with the inputs I'll check it out! on the question of the main character's jump and movements, it is inside physcs_process(delta) we used the move_and_slide() function for jumping movement, to check if the character is on the floor we didn't use is_on_floor() but a raycast like this was more guaranteed. there will be no glitches, anyway very nice to know that your game was also made in godot, so I would forget about the third level due to haste. recheck the game.
