Thanks for the comment. The pickup detection hitbox was meant to be replaced with some something a little more intuitive but I didn't get around to it by the end of the 48 hour deadline. Do you mean the 4th stage? If so, that was the stage that I had the least time to iterate. In a full version of the game, I wouldn't increase the difficulty so quickly and would instead be looking to introduce new enemies and items to vary the challenge.
