I really like the concept! Feels like Splinter Cell meets puzzle game.
The only gripe I had was that it feels a little bit slow to play. Maybe let the player hold down a direction and/or speed up the animation a little bit.
Thanks for the awesome feedback. Actually I tried to make the game faster but it did not feels like a puzzle game in my opinion. But I think I will try to make it faster like holding a button down. Cheers !
