It's a great idea! Echochrome is the closest I've seen to this, and yet it's still different. Will you make some manner of level editor? I'd love to play with one.
When I came up with the idea I searched the web to see if someone else had already done it. And Echochrome is indeed the closest thing that I found. But as far as I know using the isometric tiles for the optic illusion hasn't been done before. I think that's strange because the technology already allowed this since early arcade games, but hey, I'm not complaining
Unfortunately there won't be an editor in the first release. I'm currently putting all my energy in finishing the game. But an editor is probably coming afterwards. Some of my friends made some levels for the game, and they seemed to love creating those
(using the non-userfriendly one that I use myself...)
