This one was definitely a thinker! I like the concept behind it though! Your tutorial walkthrough was very good as well - I always a appreciate when people take the time to add that to their game jam games (I unfortunately didn't get to it this time around). I really have no constructive feedback on this one as it feels like a complete game in itself. Maybe give a more casual player the option to play without the timer?
Regardless - nice submission for the game jam.
