I think this is a great start for a sandbox-y game! Some basic instructions would help me understand how to play. I liked the flying witch, but wasn't sure what the enemies were there for because it didn't seem like there was a health bar or some lose condition for getting hit. I could just stand there getting hit by ten enemies and there's no feedback on when I'm low health and it just gives me a game over screen without any obvious feedback. Just needs to be clear what is happening to the player.
