i enjoyed the Rush Hour-style puzzles and mix of 2d characters against 3d environments. as the game is now, i don't fully sense from the gameplay a story about climate. tho reading from your development summary, the production process seemed tough so wanted to commend you all for doing what you can despite those challenges. the art and amount of thought expressed in your development reflections show potential for your game so hope to see more come out of this project!
also, wanted to point out a bug in the second level, you can walk towards the player between the trees on the right indefinitely so seems like there should be an invisible wall there
