THIS IS INSANE!! the way you animated the bitsy bg tiles when moving is so clever honestly! I'm so curious how you arranged the rooms and exists and so on for the light effect too!? Absolutely delightful! specially working with an older version of bitsy :0
Thank you for yout kind words! I'm really glad you liked our game.
To be honest, the whole thing is pretty simple in terms of how it works: we just treated each room as a separate frame of the animation, filling it with tiles and changing color pallete if needed. The submarine serves as an avatar, and it stays on it's place, but everything around it changes when we move to the next room. Took us a lot of hours to animate it all, but judjing by your comment, it was worth it :)
