Really good game, and good mecaniques,
it's really simple to understand the concept of this game. a few sec in the hand and we know what to do.
it's true that there is not enought levels (but it's normal ^^).
if i would need to change something i think it's the number of try in the firts levels to give the player a chance to understand with not losing imediatly.
If there is new levels i will love to play it, i think you have a good casual game.
Great jam !!!
