I got 4 of the blue thingies and completed the game. Took a few minutes, but was a rather good experience. I actually dove right into the game with only the understanding that I copy left click and use WASD. Most of the time when I don't realize the full controls, I'll go back and check. This is really to see how innovative it is for gameplay, which I felt was fairly straight forward. Then when going back and realizing I could just use the right-click to remove and bring back a piece, I was more interested in continuing. The pacing of the game felt challenging, yet fair. I felt good about getting the little blue things, and completing the game felt pretty great. The music was nice and cute, felt like it fit well.
