The character designs are so coooool! The art in general is just amazing; I love the look of the characters, animations, environments, and UI. The game has a cohesive vibe, and the difference in mechanics between the two characters is very interesting and fun to learn.
I encountered a small problem in the second area: If you switch off of a character while standing on a platform that only they can see, they'll fall through and get stuck there, rendering the player unable to move that character when swapping back. In the second area, I stood on top of a trunk platform and switched, causing that character to fall through and get stuck inside. This bug is easily avoidable though so not a big deal. (If anyone else encounters this while playing, hit the restart button in the menu to go back to the beginning of the level).
If you continue working on the game, I'd recommend looking into that bug as well as adding sound effects.
Overall, I thought the game was very impressive visually and had some super cool puzzles! Great work!
