Are there any other abdl games like this? I am intrigued with this weird fetish.

this, not exactly. There isn't a lot of VNs with even a hint of ABDL in it, and those that had it were all eventually dropped. Still, there are other names to check out :
https://f95zone.to/threads/messy-academy-version-0-06-messy-studios.36344/ : which I was very skeptical of at first, but seems to be heading in the right direction. It's got actual art being added to it, and it also has sex! And that's very rare.
https://f95zone.to/threads/diaper-quest-v2-1-aika.12243/ : a little hard to classify. Not a VN, kind of an RPG, but also not really.
Now for games that aren't on here :

which is probably my favorite in this genre. Cool art, cool concepts, fun dialogs. But it's not on here, so you have to find it and, unfortunately, the updates do take a while. Also

is making a rip-off of it, but with lesser art, lesser writing, and the same concept.
There's also

that's pretty good and getting close to completion. Only drawback with this one imo is that the RPG aspect is very time-consuming and gets annoying after a while because it's only running around anyway. Still, this is the one with the most content in it.
Finally there's

which was more into DL/humiliation. It had pretty cool ideas and a mood that's completely different than every other game in this category, but with two and a half years since the last update, I think it's safe to say it was abandonned... right when it was getting interesting.
Voilà, though there were many other projects, most of them were either at a 0.0.2 level of contents or most likely bugged af, and immediately dropped. These are the fives I'd consider "worth your time", so check 'em out why not.
(also there seems to be a bunch of more "story-driven/VN" types of games in japanese on DLsite, but don't expect any kind of translation for any of them ever)
