i think it is possible for the second level (though its actually just the first level, the room you start out in is just for you to figure out the controls) to be beaten, but incredibly difficult, the key is to just spam really really fast, the players hitbox is smaller than the enemies so i wouldnt say its "physically impossible"

one of my friends tried it out in call and they got past the first obstacle by just sticking to the wall and pressing very delicately but quick

i made a save state version for them to beat the level in (different from the practice version up on the game page, lacks some other features i added in the practice ver) and while they did use a save state almost after every key press, they got past level 1

also i dont think anyones figured this out but you can press space to stop moving
