Cute and relaxing puzzle adventure game! Straightforward tutorials. Art and theme are complementary. I tried to break the game on purpose and I somehow got F1LL over the stone wall without solving the puzzle. This resulted in me getting stuck forever without a way to solve the puzzle to lower the wall. Due to this, I suggest implementing a reset button where B0 and F1LL respawn at a certain spot depending on the area you are in. This way players can't abuse this button to solve puzzles but also will be able to respawn in case of bugs/glitches where you lose a character. Overall, this was very cute and pleasing for a relaxing adventure.
