thank you for that valuable feedback!
i ran out of time, but had intended to add difficulty levels, with an easier mode with a longer timer, and an impossible mode with a very short timer and no sums displayed). it would technically be possible to play a token every turn, and likely win points when they would randomly combine to 43, but that wouldn't be much fun so i sort of assumed a player wouldn't do that. definitely room for improvement, and renewing your "hand" only after x turns is an interesting idea for sure!
thanks for playing and glad you enjoyed it a bit! :)
