The holopad mechanic led to some interesting puzzle solutions. Having to plan your moves in advance for the hologram was pretty cool. I felt that pushing the hologram felt weird though. For example if the hologram was going to move on the space I was occupying and I issued a command to move onto the space the hologram was on we would pass through each other instead of me pushing the hologram. Lastly, I'm not sure how the big smile level is supposed to work. The right button didn't seem to do anything so even when I get the hologram to push the box onto the right button the exit is still blocked.
