1) Transparency is too high to make this a worthwhile game. At least in Where's Waldo you could always count on seeing Waldo, as he was never transparent or shaded black.
2) Tab key = win.
Well, as a first submission to Kong it's got some decent gameplay and animation. The color schemes need to be fixed - you cannot even see enemy bullets on levels 2 and 3, and of course there are the previously mentioned collision issues. Still, this game is obviously an original effort; keep up the good work!
I can end with 40 coins pretty consistently now; the 41st coin is hard to get as it's at the very end, is moving, and you have around 1 second to click it. :(
I hated the physics. Respawn invulnerability would wear just in time to get nailed. Also, you devs have GOT to realize that holding the spacebar + left arrow + up arrow on a standard keyboard means the "up arrow" keypress is ignored.
