Lot of depth and complexity here, impressive stuff! Loved the 3D character models as well, big props to Jayjay.
At first I was just trying to fill in the slots with whatever I could find. Once I started losing (sometimes badly haha), I learned how the bonuses worked by inspecting the pretty arrangements of my opponents, which was a game-changer. Definitely should've opted to read the tutorial earlier in my playthrough but still managed to recover to reach victory!
Really liked how the game encourages experimentation + strategy by trying out different layouts via storage, too. Great job :)
