Banger of a game! The artstyle, music and gameplay are incredibly polished, so well done on that! Loved playing it for a few rounds, trying to get better. Overall I have no complaints, maybe a very minor one that after selecting a card, it would be great if I could unselect it if I didn't want to place one (in general, I don't mean switching to another card).
I had the same bug as Malic, after unlocking all lanes for two sides, the game starts glitching. The 3D view starts flickering black, until at one point it turns entirely black. The UI stays visible all this time, tho.
