Color Assembler (my game) is now on Steam Greenlight

Definitely some similarities in terms of shapes, interface and puzzle type play, but only first one even deals with color, though that definitely has some similarities with how those puzzles would be solved. Another one along these lines is http://store.steampowered.com/app/286380/ though I had initially thought it used color mixing and it doesn't that one is about sequencing. Oddly enough I have all the similar games you linked grundig, though don't have the one I linked, and I would still likely enjoy the game the OP is trying to get greenlit. Upvoted here.

Normally I would have used a picture but I think you're worth a .gif...

You do know that "similar" art style does not mean "similar" gameplay / type of game, right? All those games have geometrical shapes, true, but that doesn't mean they're rip-offs of each other or whatever you mean by "similar games".

None of these games use the same mechanic for gameplay. They involve shapes and/or colors but don't play the same way.

But thanks for pointing me to some interesting puzzle games. I'll put some of them on my wishlist :)
