A good puzzle game, but the mechanic is a bit simple i feel.
That being said you made a great use of it and the lvls are well designed, some of them are really tricky, i loved it.
Maybe pimp up the music and sfx as i think it is very important for puzzle game.
Gaphics could be easly improved to but it works like that.
And to be really picky about the game design choice. I think the idea of a fox chasing a rabbit makes sens... but... why is the rabbit following me if in run away ?
See what i mean, nothing terrible but again, it broke the immersion for me. I would like the rabbit to only be able to go toward a whole but that would make the mechanics much harder i imagine.
Anyway, great job :)
