If you liked the comedic part of 'I picked up a star on the road', then you might like zombie detective aswell.
I find that they have the same 'weirdness' of humor and ridiculous moments, some serious parts that just escalates to something funny.

Both have their fair share of tender moments aswell as comedic slapsticks- although ZB comedy may be slightly different and occur more compared to IPUASOTR

Both presents and centers around a ML and a FL

Pretty similar concepts, apocalypse with zombie like humans but except they're not just zombies and have been consumed by revenge/anger/dark desires and gotten superhuman abilities.
One of the differences is that in Sweet Home, the characters are pretty much "stuck" inside a building but in Dark Hole it is shown more open world compared to it. However even if you do not get to see much of the outside world, there is still much suspense and action going on.
Overall I would really recommend Sweet Home if you like Dark Hole, it may not be as chaotic in terms of a zombie-like apocalytic setting, but it bears similar concepts to Dark Hole and just as much actions fighting and a feeling of danger against bigger human turned mutants.
