(Disclaimer, I playtested this game just before release, so take that as you will)
Slimes is an excellent, excellent game. A really unique art style that works super well, really interesting and involved gameplay that really encourages strategy and guns, and a really great and satisfying story is told.
The conflict and concept of a 2 person team who hate eachother works well in the narrative and even down to a gameplay level - one skill Julius might use will debuff Healer, and vice versa.
I hope this goes down as one of those classic RPG Maker games, it's weird, some of the most impactful games for me that I always fondly remember are RPG Maker games (Ib, Yume Nikki, The Endless Empty, Nepenthe and now Slimes).
TLDR, game is great and the PDF is an interesting read too!
