Hey G0ldent0y ! I remember the sick rhythm shooter game you did last year !
This card game has a pretty interesting concept ! I have to say the first phase where you select your cards is a bit tedious, making a deck of 15 cards is a bit long especially when you don't really know what is good or not. I think it would be more fun to get a default deck and change it as you play.
The colors system is pretty interesting, as others sad it seems like it's not always working properly, but I like the design philosophy ! I think it could become something really cool with some balancing and debug work !
