I thought I'd try this game out for 10 minutes, and after tens of hours and many fun evenings I am still discovering new strategies. The gameplay is dangerously addictive! The "pictures from around the net" style feels a bit nostalgic to me, I like it. Even if some of the central sexual themes are not fully my thing, there are lots of choices and variety.
I know that I'm a bit late to the party, but I really hope that you still have plans to release updates! I would love to see an anime variant for the last few cards that don't have it (mostly for Magical Boi, my favorite dual transformation). The endless mode could use a +1 TF damage per level scaling for the bosses and maybe an extra power for the regular opponents every four levels or so (I went infinite with a few combinations). A list of highscores for endless mode would also be a welcome addition. The only major thing I recommend for card balance is to give a 2xTF effect to an expensive late-game card in the default collection to open up more options for players to take different sets (2xTF is absolutely necessary for any strategy in endless mode and is great in story mode too). A final bit of polish and some small bug fixes, and I think this can become one of the games I'll keep coming back to for many years!
Thank you for all of the fun, this is a truly excellent game!
