I really enjoyed what I was able to play. Unfortunately I struggled to get far by using just the trackpad on my laptop (I really wanted to play more).
The game is simple but you did a very good job of mixing things up with the different types of goals ('reach the flag while staying silent' etc).
The graphics are perfect for this kind of game, keeping things clean and allowing the player to focus on what's important. Good animations really gave the movements and actions a satisfying feel too.
Nice work.
