This was really cool! I like the vibe, and each of the different worlds were very distinct from each other. And I'm going to come out and say it... I like tank controls! I think it's the only way you can do these types of fixed camera games and have them actually make sense.
The character felt great to control- however there were a lot of areas where it was easy to completely lose track of yourself, either behind geometry or from being able to go off camera. It made it a little difficult in some areas to navigate, or just to tell which directions were another screen versus a little bit of empty space just off camera.
Overall, great job though! Would have been a good moment if, after the last painting, the ghost kept following you until you got back to the front door lol.
