Very nice game, thought of the treadmills too but didnt have the time in the end. Super very clean presentation idd, nice complementing music, sweet transitions.
Offcourse there is the direction problem had the same comments. Obvious seen the title afterwards but initially didn't really understand the objective. Some puzzles I solved randomly without using allot of the tiles. And I would go to next level automaticly as well indeed!
Really nice job guys!
