Interesting take on the theme. Making the characters join together into something that makes sense is unexpectedly rare in this jam. The level makes good use of the abilities of the players.

Here are some critiques:

• The cloud is only needed at the start and end of each level. I think there's potential for the cloud to have some sort of ability too (e.g. not affected by gravity)
• It's difficult to get the box out of the pool.
• On the level with 2 pits, there's no clue showing which character should go down which pit. Going down the wrong pit kills the player, making it unfair.
• The colliders of the players are rounded. This causes the players to not act as a proper platform. It also allows the player to slip up the blocks that are on the same jump height, which I think is unintended.

Great job finishing your (first?) game!
