Awesome games !
* Brofist *
It's pretty cool!!.....thats all i can say :p
I like it. An enemy would be cool though. It was probably just me being stupid, but I couldn't really tell if would be able to walk through or drop down into a different panel until I either walked through or got buzzed at. Cool though.
The zone changing system is the best part, it's like a puzzle piecer in a puzzle that is intertiwined !
I ussually don't like puzzle games, but this is awesome!
~ I think you should extend the puzzles, at the end there is around 10 zones, I think, if you added more levels, it should transfer to 20 or 25 or higher.
~ Implementing a puzlle creator would be awesome!
~ Add more door varients (Red door, green door, blue door) and more keys. Change up the level coulours a bit, if possible.
Would be 8.5/10, but since I enjoyed it so much, 10/10 ! :P
