I really liked this one! Just using the arrow keys made it really fast to pick up.
I got a little lost on the last level, but as soon as I realized the twist, it felt really satisfying. I still have no idea how you pulled off the optical illusions. I figure it has to do with the camera positioning.
The music also sounds really nice and I like the gentle sway of the ship & interactive menu.
One thing that I noticed is that at the start, you can walk into the ship. I also didn't realize at first that when it said "jump to exit", that meant jump off the edge. I assumed that it meant press space bar, as that is usually what jumping entails.
Great game!
