(Uhh sorry there's some spoilers I guess, I tried to write around it but there was only so much I could do) The first wildcard is a really funny game mechanic, the imposed time limit, the "whee", and the loudest explosion I have ever heard in my life combine for a truly unique gaming experience. My only complaint is that I possibly would have made it a random wild card rather than making it always appear first, only because I think the fear of the snail appearing could be really funny and chaotic in its own way, rather than the inevitability it currently is. I do get wanting it to appear, maybe randomizing it between the first couple would work?
It's also pretty funny that one of the wild cards is another one of the potential themes, unfortunately I'm not good enough at match-3 games, particularly on a time limit, to be able to conclusively say there is only one but I'm pretty sure. I did find it a bit difficult generally, but I still had a fun time!
