For those that know of Camel/D-gate, they got together with ASIMOFU (Fromage, if people still remember that game) and worked on a vore game called Millia Wars about 6 years ago that was kinda small and was bundled up with two other small games.
But now, they teamed up again and came out with a stand-alone version that has more playable characters, enemies, and stages.
ミリア戦記DX [D-Gate] | DLsite
You can get the demo from that link by clicking the yellow button below the preview pictures, and it also shows the file size. If you can't find a way to buy the game from the DLsite, Camel mentioned that the game will appear on the English DLsite sometime in the beginning of January, so I'll give it about a week or so. There's only the first part of stage 1, you can only play as 2 characters, and there are only 4 enemies in the demo.
Once again, this is a HEAVILY vore-centric game, so careful about that. There's a bit of yuri in here too with the monster girls. If you need a comparison, It feels like this game is inspired by the Metal Slug games, especially with the how the rabbit girl plays. You don't die in one hit, however, as you have a HP bar. You also have an SP bar that you can use a character's special move with. But as your HP goes down when hit by enemy attacks, your SP bar will be your only defense when you are grabbed by an enemy. It's not constantly draining, but a bit of it will decrease when you are grabbed. If it's at 0 when you are grabbed, your HP bar will then go down, and you'll be pulled into a vore animation, which decreases your health even more. In the full game, there are only a couple enemies that do not have vore animations, and will do something else when you lose all your HP.
Controls - The game uses asdzxc as the keys to use. Z to jump, X to attack, C to use a special move, A to skip any grab sequences, S for the pause menu, and D to toggle the zoom function when you're grabbed. Each character in the full game has their own move sets, but they're explained in the game when you select them, so I won't waste time explaining them.
If you like vore, then I wholeheartedly recommend this game. It's probably my favorite vore game so far, and I hope they plan on doing more with this series in the future. Maybe an update is possible, but we'll just have to wait.
