The puzzle design of this one was pretty good, and it's quite impressive that you were able to implement so many levels in the 48 hours given. One comment I would make though is that I feel like the addition of 4 player characters comes a little late. I think I would have preferred that to be introduced a little earlier. I also wasn't sure if you were supposed to be able to move onto a gate tile in the same move that another player moved off of the switch that activated it. Sometimes this worked, sometimes it didn't. I was also a fan of the art style, it reminded me a lot of Minecraft. Overall pretty good.
