To say the least, the game wasn't what I expected.
The first thing I want to point out is that the game is very barebones. There's no tutorial or a story. You choose one of six characters with preset builds and decks and try to beat the other 5 characters with it. If you win two out of three times, you get three extra points to allocate and move to the next round. If you win all 5 matches, you get the CG for the character, which is basically just various stages of undress and a cumshot. All of it in the same pose.
The problem is that I had no idea what the hell I was doing the whole time. The gist of it was that when you use a card as intended, it either equips onto you or it does as its described, and then poofs out of existence for that round. If you use the card to attack, and its intended effect is not to deal damage, it does some damage based on one of your stats (I think?) and goes back into your deck. Sounds simple, right? Well here's the thing, I don't know how the stats scale. I have no idea if it's worth playing certain cards. I don't know what stats I should be raising at the end of each match. I somehow won and unlocked the first CG, but it didn't feel like any strategy was involved. I didn't bother trying to unlock the other 5 girls' CG. The one CG I saw was lackluster and the gameplay was confusing and unsatisfactory. Going by the screenshots, it looks like the other characters either share the same deck or share most of the same deck (which only has like 20 cards). Considering that you need a minimum of 10 wins to clear a character, that's going to feel repetitive really fast.
Boring, confusing game mechanics and unsatisfactory reward.
