I actually cant believe you did all this in a week, CONGRATS. Especially the artworks.
OK SO, first of all its extremely cute and fun to play with friends.
Few issues i found is that the deck on the left starts piling up so much after a couple of encounters that you cant physically see what your teammate is placing, neither can you click on the cards behind the pile.
Also the black cat, it does not work cause of when you programmed the buffs/effects to take place. It always divides the attacks of other cards by 3 since the starting damage is always 0 (aka a positive number).

I think it's a bit of a stretch on the theme, as in, the risk it for the biscuit isn't part of the MAIN gameloop but still present when you choose the reward so it's fine.

Other than that, GOOD JOB, we had ton of fun trying to get the damage score to a 5 digit, AND GREAT ARTWORKS
the pings and lil paws countrols are a nice touch

also shoutout to Snarlface the Unneutered

Nice work! Fun gameplay and I really liked the card artwork. That's a lot of assets and content you guys were able to make in a week.

There's a funny bug where a card will fling up and down if you have the mouse at the very bottom of the card. Feels like exactly what a cat would do with these cards.

I liked the game a lot, impressive work! Like others mentioned I would loved to have an end-turn button. Also I didn't get the multiplayer aspect of the game. Congrats anyway!

Really well polished! The gameplay loop worked really well and I think it's genuinely incredible just how much work you've done in a week, from the art which is incredibly well fleshed out and designed to all the mechanics. It reminds me of live card games like exploding unicorns, and could be adapted as such if you wanted to. The main bits of feedback I have are 1) I wish I could have skipped a lot more and taken less time, especially when I'd built my deck and was waiting for the round to finish, and 2) The bosses did more to combat you. It felt a little awkward and passive with the only challenge being a timer - some sort of a turn based battle system could have done quite nicely, with the timer as well. But seriously, really great job!

I really like the medieval style and the matching background music. It’s fun that we play as cats trying to steal biscuits from dogs. I’d love to have an end-turn button, because waiting for the full turn time can be a bit boring and slow.
