The art and sound is amazingly top notch. Unfortunately the gameplay is some of the most average, mediocre nothingness of 2D platformers/boss rush games. Everything is so intensely shallow. The extremely few platforming levels seem to be thrown as if they either ran out budget, that seems to be most entirely spent on art and sound, or through a low effort attempt at adding variety. In addition, the difficulty was most definitely a low effort attempt at adding length to the game. Worst case, you die once or few times and in doing so you recognize a boss' pattern. Rinse and repeat every level. The game is like 3-4 hours in length, on normal. Granted, hard adds much onto this playtime even if it is lazy as hell design.
