Very awesome puzzle game! The controls and instructions were clear from the get-go. Gotta say I'm very impressed with the UI, menus, and visuals! Quality of the visuals is something I would expect from a full-final release game. The puzzle mechanic was very intuitive, I kept getting frustrated at myself particularly for forgetting to press 'K' every 5 steps. Also, I got stuck at level 10 and I'm convinced that it's impossible to beat. Haha. The music was nice and calming and the sound FXs were pretty neat too. Fantastic game overall! Really does feel like a full game!
