First and foremost, I really enjoy gacha games and I can say that the game in that regard(The Gacha) is REALLY lackluster.
Let's start with the Cons:
I believe there are not enough characters to make the gacha shine and the summoning system needs a bit of work.
I also feel its too punishing for the type of game its trying to be.
A 3 in 100... is a bit too much, I do understand its for the gacha, its just way too low since there's no real money involved at all there's no reason for it to be so low.
And the rewards for dupes is meh, its bad. When we get those we just have a pile of them without any proper use, since it only gives the basic books.
The good stuff:
Oh boy Insult Order does have good visuals, its good to have a break from the koikatsu visuals.
Its using the sounds from Insult Order and they do the job.
The interface is nice and feels reward getting the dailies and other things, small things but it makes the overall experience much more enjoyable.
(The horrid hover level up system needs to use its mobile counter part please, I'm always hovering about with my mouse its just terrible.)
Visuals 5/5
Character Design 4/5 [GIVE ME MORE TAN TSUDERE BABES]
Sound 4/5
Gacha System 2/5
So its a 3.75 out of 5 that I personally round up to 4.
I do believe the devs can turn this into a good Fap Game, given the content and time. The goals... could have been less costly, but I've seen worse.
They also seem to work fast with a day 1 update fixing big issues, hopefully we get a better gacha/material system if more characters get released and a better experience in future updates.
