I actually never played Puzzle Fighter, so the gameplay was totally new to me. ^^ I like it a lot, and have kept coming back to it. My main feedback is that the green and teal are really close in color, so can be a bit of a strain at time. Maybe choosing colors that also have more brightness contrast between them, or including a unique pattern for each color, could make it a little less reliant on hue recognition? Either way, you pulled this off well. Congrats!
