first off incredible job!! cant believe you accomplished all this in just 72 hours that is a very impressive feat. the music, SFX/VFX, art, core gameplay, etc etc are all very polished and i could see this being a popular mobile/browser game with a few minor tweaks. Its very fun to experiment with the different tiles and the mechanic of tiles influencing your future cards is an excellent unique twist on the genre.
Some minor improvements I would suggest, without the time constraints of the jam, would be to have every tile interaction do something, as its really cool to discover all the interactions and a bit disappointing to see "no effect". One that comes to mind is I wish rain on a mountain created a waterfall tile, and maybe a flood on a mountain would cause a Niagara falls super waterfall. I really liked your evolution line from grass to swamp to morass. An achievement system would be cool too like in those combine element games for the sense of accomplishment of discovering all the world has to offer.
This was an inspiring entry to see what is possible in just 72 hours (with the requisite skill and hard work of course haha) and I think you have a great foundation for a commercial project if you wish to pursue it.
