One direction sliding puzzles like this are not new but this one is semi unique (at least to me) because of the use of the six sided shape that really compliments the genre. I mean, I have seen games like this that only uses squares that only gives four directions or path to base your moves from, but in this one, I have six.
It may seem like a small change but it really impacts the way your calculate your moves breaking the routine that is common in this types of puzzles.
Overall, Hexep is a simple, straight to the point challenging and entertaining. Meanwhile, here is Hexep walkthrough showing solutions for all of its levels.
