I love the concept- and it's cool to discover what everything does and new and exciting ways to die (blown up by barrel? check. Squashed by block? check. Plummet into the void? oh yes...). Big problem I had with this was the janky character movement. It feels both unresponsive and floaty. There's no way of turning on a small block, for instance, without falling off the other side, and there's a slight delay after pressing the button before something happens. I always appreciate controller support on NG tho :)
Update: Tried again using keyboard- movement great. Think the game just doesn't like my Logitech gamepad. Weird!
