Ok i'll try it for you. :)
feed back is great - the sound and shake when you fly off the screen or hit a block
music is good and I like the spacey backgrounds
picked up on the core game play mechanic very quickly and it did not feel like a choir to figure out
also this level was very close to being a quiting point for me
i forgot to screen shot, but level 14 was a welcome break from pace
I ended up playing this for fair bit longer then i intended to (quit when a family member needed a hand) -so that has to be a good sign
You must of put in a lot of effort making this and it shows. I am a amateur game makerer' my self and i know that would of taken me a lot of time and effort, I'm impressed!. You could probably monetize this game (further?).
Some thing that might make it better-
A few breaks from game play, do remember how in old pacman there would be a small cartoon cut-scene every few levels? They were silly and seem meaningless on the surface, but they serve a purpose - relief.
Also i was going to say add a hint system, but right before i quit i played a round a bit and realized you already had one! Good idea since the game gets pretty challenging (also well done for coming up with such challenging levels).
In conclusion, you should be very happy with your self, its a very solid game and I was genuinely surprised by the quality. I only started with itch.io a few days ago and i expected the quality of games to be only around about the same level I could make my self, but this was a lot more polished than I expected.
