It's rare to see pixel games so funny. Too bad it doesn't work on Firefox.
Also, in Chrome if you click outside of the screeen THEN alt-click the game you end up showing the loading screen - bad HTML5.
Another bug: when you level up and assign all points to any team member, the aura dissapears for the opposite player (ie assign all to the 1st, and no.4 loses the aura). Too obvious.
Suggestion: make some of the empty chests drop extra fish.
That would make getting keys worth your time, and would avoid the annoyance of getting empty chests until you realise you already got all clothes.
That, or stop spawning keys after you wardrobe is full.
There should be a way to upgrade/refill the running bar whenever you finish the prior level with more time - otherwise it forces you to do ALL 4 levels in one go. Not enough time for the last level.
Congrats, the graphics and gameplay are perfect. I do miss the climbable trees from the first part, but the caves are way better.
Also, HOW did William buff up so much when Sly's the one doing the hard work??
