Obscure chinese eroge, cannot find origin

[kikones34]

Hello all! The other day I was sorting my extremely messy eroge folder, and I found a demo for a game that I had forgotten existed.
It's an action, pixel art eroge where you give orders to some succubi to defeat the enemies.

Spoiler: Screenshots

I've tried my best to find where I got it from, but all I have is the name of the folder "Advancing Monsters DEMO_V3". There's no info about the creator in-game, nor in the TXT files included with the game. I've also tried searching for some of the lines in the changelog, but there just seems to be no trace of the game on the internet.

Well, now I'm really curious where the hell did I get that game from. So, if by some miraculous chance anyone that sees this post knows about it, you'll make my day ;)

I've uploaded the game here in case you want to try it yourself: https://mega.nz/file/aJFh3AKA#s3SnbE1as4hCB2kaGD6Japegl9lTqv41V736SDBZwOA

I managed to find the game in the end, leaving it here in case anyone's curious.

Devil Leigeon. I have this. This game and Drain Mansion are games that get a lot tougher later on.
