Very creative!
I was very impressed at how fun this managed to be! I was at first thinking how it wasn't that of an original idea, but I liked how the colors and the words inside seemed to be designed well. It would've helped if there was some music, but the sound effects were well done enough. The gameplay is pretty simple in nature, but it knows how to be complicated. If there's one hit, it's over, and they can't be in seperate squares. This is a pretty interesting puzzle game that manages to be easy to understand, yet also difficult as you go on.
