thank you for your feedback! i definitely ran out of time for some aspects! and agreed, a tutorial intro could have really been useful!
as you might have seen in the settings screen, i originally meant to add difficulty levels which would've allowed the player to start with a slower-paced timer, to get the hang of things.
as you never know if the opponent will play a token, and what that token's value would be, there's definitely some randomness involved. when you see/calculate that the combined total is nearing 43, it might help if you can manage to have lower value tokens in your hand, and try to send one in when you calculate that the opponent's tokens allow yours to reach 43.
