Vertical manoeuvre pigeon got me laughing good.
While it's a shame that it's unfinished, what's in here is very well thought. The traditional platforming mechanics are functional, but the ideas brought to the table are what make this project special.
Having this duo of birds have different functionality when together and separated really sets up the place for a lot of puzzle mechanics, and it's even better that some are not just "this character can only do X, and the other can only do Y", but that both have different feeling and limitations due to their size and even weight.
The best puzzle platformers use the limitations of the characters to their strengths, and having two characters - which actually can be considered 3 if you count their combined form - opens up a lot of opportunities, which would be fantastic to see explored in the future. Great job here! 🐦
