The game was fun enough, though I think the expiration mechanic is half-baked. Honestly, it probably would have been better without it. Also, I noticed in the description that it describes there being two ticking clocks, which is a little bit misleading. To my knowledge, there is nothing telling you to speed up or slow down. I also think the game would have heavily benefited from a way to control what was/was not in your deck.
This is very impressive for being a 9-day thing! The art is very good, and I could see this concept going far.
