Demon Angel Sakura is probably a pretty decent game if you're into vore. As a series, it's a platform shooter with a heavy focus on the various types of vore and/or body absorption.
Story wise, it has a story to string the various stages together, and it's okay I guess, but nothing super notable as porn games go. It's not atrocious either, and doesn't take up too much time, so it's overall a neutral thing to me.
As for the shooter/platformer aspect, it's pretty difficult, especially some of the bosses having fairly difficult hitboxes, which may require multiple attempts (or I just suck). It starts as a boss rush game, and by the second entry, has become a full platform shooter. Overall, it was fine if you're willing to put the effort in. Minor enemies become more of a thing as the series goes on, leading to proper levels, and some even get their own H scenes.
Now, porn wise, this wasn't my thing. Between the soft boi crossdresser characterization of Sakura and the focus on vore, I wasn't into too many of the scenes, but what was there was pretty well done. The minor enemies get way better as the series goes on, even getting entries in the event room for later viewing. It's a view on loss system, which you either love or hate. I like that, so there we go. If the idea of a tiny crossdresser getting turned into goo by peoples' sweat, or eaten by butts, or stuff like that is a hard pass for you, DO NOT TOUCH THIS GAME. Or just be veeeery good at shooter platformers with slightly dodgy hitboxes. The art isn't bad, and gets noticeably better as the series goes on, as do the animations, although they begin at a pretty janky state, particularly the first game.
Anyway, despite being a little buggy in places, I'd call it a solid series for people who like being eaten, and an alright one for anyone else.
