Really nice game ! I like this kind of challenges (make me remember of Mario 64 DS xD) Is there any harder difficulty past level 25 ? I feel like it's been some time that the difficulty hasn't changed
The last difficulty level was in level 15, if I make it harder than that, every swap will happen in 0.1s, and that was almost impossible to track where the card is, so that's why I leave the max difficulty at level 15, where every swap happens between 0.3s and 0.4s.
