I tried your game and I only could beat the first boss, I really liked the design of the second bossfight and those tiny useful details like the slow time while you change forms. Some things I would like to see improve are maybe adding a dash, a Boss' Health Bar, a tutorial (I had to pause the game to look at the controls and that is not very intuitive) maybe adding it as part of the enviroment could help and making the buttons bigger or easier to spot
