Would it? Any new game is demanding compared to the hardware of the past. And noone is interested to invest lots of resouces to optimize it for slow hardware. So if the requirement would be f.e. 68060+RTG how many sales would be left? This game looks not so demanding so it could perhaps run on a lower configuration but that is the way most people think.
It would. If somebody wants to do a proper classic Amiga game. Look at the C64 scene. Sure, more simple architecture, but they released some nice games over the last 3 years and more will follow. You can't made money out of this, but it's possible to do nice Amiga games with the right effort. No homebrewish looking games for fast, mostly PC like, Amiga systems.
