itch.io

Syahata's bad day is as close as you could get to HTA, other than that? Not much- I've been trying to find those games myself.

Syahata just got an update like a month ago and it's quite simmilar. It's a variation of a zombie apocalypse game, but there's a lot of different enemies and after completing the game you get gallery which is nice. Highly reccomended. 

Another game could possibly be parasite in city, but it's not on itch and I just haven't felt so adventurous to download it, but some people vocally praise it, so it could be worth a shot.

Then I could probably find some other games, but they're mostly unfinished and abandoned.

Dunno, hope this helps
