<i>&gt;I mean, what&#x27;s the hardest game ever made? Probably if you&#x27;re really picky, some ultra obscure shoot em up or kaizo esque Mario ROM hack.</i><p>Probably some bullet hell game which requires pixel perfect movement. Such as: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nscP9QpXoFM" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nscP9QpXoFM</a><p>I&#x27;m 99% sure near the end there (the last minute or so, last phase of the boss) it is literally unbeatable without buying more lives and if this wasn&#x27;t an arcade game that allowed purchasing new lives, I don&#x27;t think it&#x27;d be beaten by anything short of a tool-assisted run.
