I'm really happy you liked it! Yea a couple of puzzles are a little bit more tricky but because there are not a lot of levels I tought it could be a little bit more challenging.
Eheh! The story will be amazing.
Ps: if there are multiple shortest path its not a problem for the puzzle itself, in symmetrical levels there are always enaugh tiles to block in a symmetrical way. Otherwise is "usually" clockwise from top-left.
