Bloody amazing. I can see the game took some inspiration from Slay The Spire with the map, relic, and card system but added a little spin with Megaman battle network style combat.
The sound design and music were great and the spriting work was beautifully well crafted. One thing that I found to be weird was the card's flavor text reference. Seriously, this makes Gintama look like a college essay. I'm half expecting Apotheosis to be a card. Not that I mind it, I actually found it to be quite charming. The gameplay, goddamn, the gameplay. If you like the simple yet diverse card system from Slay The Spire and enjoyed the fast-paced combat of Dead Cells. Well, I got good news for you buddy! It also includes anime girls, free of charge.
However, just like every single game created on planet earth, it has flaws. So here are some flaws.
* Relic that you get from opening the box of Touhou should be skippable. Mainly because some of the relics can either make or break a deck. Or is just plain bad like the Spaz turret. I understand I can skip it before opening it, but I always open the box anyway cause I'm always afraid that it might be something really, really good.
* Some of the descriptions of the card needs to be reworked (Like what does 100x75 means?!)
And that's it really. Aside from the obvious stuff that is more than likely going to be fixed in the final version like card artwork being duplicates of each other. The game is freaking amazing. Definitely, be buying this when it comes out of steam. Anyway, have fun when making the game, don't forget to sleep and may the coffee be with you.
