<p>hi everyone,
as an avid public transportation enjoyer and mini motorways fan ive always had an itch to make a metro optimization game, so i made this daily puzzle<p>fun part for me: after a grad pl course i wasnt sure when id ever use a sat solver. turns out here. every daily map is solved exactly with or-tools cp-sat before it ships so theres always a proven best score to chase (hidden unless you turn on hints)<p>maps get tougher through the week. mon/tue easy, wed/thu medium, fri hard, sat/sun bigger bonus maps with extra features. you can replay old maps via play archives. no account no ads<p>ive only tested with friends and family who arent big puzzle players so id love feedback. im leaving out instructions on purpose to see how well the game teaches itself<p>let me know any and all thoughts!</p>
