i think honestly it would be fine as-is, if only you got some checkpoints to smooth things out - old school arcade shooters dont have checkpoints, but they allow you to pay for more continues; the intense difficulty of them is a way to push that. Not having a feature to continue, but still having that difficulty, makes it super punishing because dying can mean getting sent back several minutes to gameplay sections youve already done 10 times. My real frustration wasnt EXACTLY the difficulty, its that it took so long to get back to the place I was actually having trouble on (the building), and repeating the entire streets section every time I want to make another attempt at that part begins to get dull. If you had checkpoints, pro gamers can go for deathless runs, but people who arent as good can still experience the whole game, just like in a real arcade shooter!
