Just finished the demo! And I fell in love with Slimes. First of all, I like the battle system: pretty original, a mix of the RPG and Survival-Horror genre; I especially like the idea of mana being replaced by ammo.
The lore behind seems very rich! I've read every single side stories and I'm digging for the ideas behind... I've been stunned by some of them, wow.
Slimes is a maybe visually a very simplistic game by looking at the graphics, but don't be fooled by it, like we say: don't judge a book only by its cover! The gameplay is fun and the characters are very appealing (my fave character is "Healer", he's a such bean!), we're getting attached to most of them very easily.
