I liked the game when it worked but often enough either enemies or I bugged in walls which made the 5th level incompletable for me sadly . Also sometimes it felt like the game didn't always acknowledge my  input. Maybe that could be solved if you make the movement trigger not only on the wart of the button press but for as long as the button is pressed? while moving the cube can't move anyway so it shouldn't change anything else other than a nicer feel when handling the cube. I did like the Level design and simplistic design tho!
