It took me a bit of getting used to to understand how to bump the ghosts around for my turret, but the premise of this is pretty cool! Maybe I just didn't get far into it before I died, but it would be cool to see more baddie variety, maybe something that puts the character in danger while they're in different forms?
Also, great 1-bit work on the pixel art! Each sprite was very clear as to what it was, and that is NOT easy in 1-bit! Plus you had a nice and consistent art style which made it very clear what was game stuff and what was background stuff and just kept it all nice and clean!
