Inconsistent art style, minimal writing during sex scenes, and very little art overall. 2 stars for having battle fuck mechanics, but they're not great due to frequently shifting styles.
Of the 2 blue slime girls, Skye is especially bad. In one fight, I saw 4 different styles. Jumping from one artist to another inbetween the climax sequence is just not great. The other blue slime doesn't even actually have unique art for the climax sequence, nor does the pink princess slime.
Then there's the pointless grinding. You want to do this? Go fight the same enemy 8 times to level up. Want to do this other thing? Repeat. Want to win this story oriented fight? Repeat that 10x.
The writing is most definitely not special. It's decent at best, mediocre at worst, and far from anything I'd ever even take a second look at. The sequences are also very short, a common trend with these games.
Just a really, really weak game.
