Really nice and polished game, shoutout to the composer of the music (she must be really talented!), I loved the classical-esque music in the menu. The pixel art is also really well done. However, the game was really too hard for me, I only made it to Level 2 in 2 attempts, I think you could adjust the learning curve a bit so we can see more of the game. Also, one big problem for me was that the hitbox of the player was not obvious, which meant at many times I wasn't sure if continuing to move right would be fine, or I needed to move slightly up or down to avoid the obstacles in a particular row. The restart screen could also be shortened, since I am guessing most players would be seeing that often :P.
But other than that I had a really positive experience, well done!
