The character is floaty, jumping can easily make you cross screen bounds, there's no real way to gauge your speed, and the bosses are forced, and tedious.
Yeah it can be kinda hard. Sorry to hear about the bosses. the character is supposed to be kinda floaty and guaging your speed shouldnt be too hard as it doesnt change.
Not bad but the jumps are tricky - it takes some time to handle the power you have to put in it.
