This game has such nice presentation, I like the really manic vibe it has and there is an impressive amount of content for only 48 hours of work.
The controls just feel way too sensitive and fast to me to do some of the things the level design requires. The main issue is that the duck feels really heavy and falls through the air really fast, which makes doing the parts of the level design that require precision at speed, or wall jumps with no ground to catch yourself, very frustrating.
I do think the really sensitive controls add to the manic feel and personality of the duck, but if you wanted to keep that feeling in the controls then maybe the level design could have been changed to accommodate for them
But the art is great, I love that the opening cut scene only uses the word quack and I love that there's a quack button that serves seemingly no game play purpose.
