I really appreciate how this game doubles down on you playing the bad guy, without giving you a way to weasel out of anything, forcing you to roleplay Julius as he goes on a slime-murdering rampage, especially if you want all the story tidbits. (I'm surprised you didn't go into more detail about that aspect in the PDF!) Given that, the ending definitely took me by surprise, and the post-credits scene was delightful.
It's a shame that I had to play through on the "easy mode" to save time, since I spent 3 hours unknowningly playing through the entire demo because it was the only option in the itch app and I didn't look close enough. I would have liked to experience the combat challenge from the late-game encounters and bosses, although the final gauntlet let me fake it a bit at least. That said, pleeeeeeease mark the full game downloads as being for Windows as well, so that more people using the itch client don't make the same mistake!!
Also the art style and music are exactly what I wanted out of a weird RPG Maker game, and it really sells the story too. I'm really happy to have played it.
