I was really trying hard, but I was just not able to collect enough packages in the normal mode, partly due to bad game design, but I will elaborate on it and give you some tips 😉
Why did you choose for the character to run from top to bottom? You have way more space horizontally which increases the time the player has to react to obstacles and packages. If you really want to stick to top-to-bottom, then at least position the character at the top of the screen to, again, increase the reaction time the player has. I often had no chance to catch packages or avoid obstacles in time, which is super annoying and frustrating.
Give the player a nice start. What I mean with that, don't spawn any obstacles for the first 5 seconds to avoid the player to instantly die. Also super annyoing and frustrating, but less because it happened right at the start.
Some obstacles spawned into each other. Not that big of a deal, but can also be improved in a future version.
Your game is stuttering from time to time. No idea what happens there tbh.
