A very well designed card game. The rules are simple but allow for a level of complexity that can make for some interesting decision making by the player. Figuring out your cards and trying to determine what your opponent will play leads to some moments where you're discarding and hoping to draw into that perfect card still in your deck. That does point to discarding being your main mechanic for control over the state of the game. I'd love to have a little bit more ability to either reorganize my cards or even alter the suits of my deck. It does occasionally lead to some frustrating moments where a card I'd want to be up first ends up being played last. Aesthetically the visuals and animations are solid and fun with good clarity on the cards, mechanics of the game, and the current round. Even without a tutorial it was fairly simple to determine what was happening and how to win. My only complaint there is that the font used for the '5' made it look a little smudgy and like a weird '2'. The sound design for the cards was good, and the music loop had me grooving a little bit.
A simple game, with good mechanics, that was executed very well! Very impressive for 48 hours and I'd love to see this concept expanded upon.
