I played a few times until 1200+ score but I do not get everything. I do not understand why black can sometimes play more than one move and why sometimes I can play only one card.
I put a special function that if you are cornered and you cannot make a move in any way, then the script would automatically make a discard. Most likely you just had a situation where you were cornered and therefore could play only one card. But I am not sure, maybe this is a bug. I will try to fix everything after the end of the jam. Sorry for this and thank you for your comment!
