Fun and entertaining game but a few negatives. The game felt like a grind after awhile. The levels were the same and it just took longer to complete them. There are a few graphical glitches the sometimes one of the blocks fly across the screen. Regarding the health bar, the coins fly in front of the actual health part (the bar), but they fly behind the part where it says HP. Another thing is after you get the first star a message pops up saying "New Level" but that's the only time it pops up. It does not pop up when you get the second or third star. It should be more consistent. I would say something about the star button but you covered that already in your notes. The last thing I want to point out is on the 12th level after you defeat the boss it says that you unlock a new Goomy even though you don't.
Other than those things it was a fun game. The music was enjoyable and so were the sprites that were created. I was a big find of the large white stroke.
