Wow, this used to be one of my favorites. A couple of questions, tho.
1. How many pearls are there in each clam? AFAIK, in original game, once you pick a pearl, clam closed forever, and that forced you to explore. I have tried to pick pearls on the first level, but they just keep opening again and again.
2. With a new life, i was expelled from the boat down just at the moment the shark was there. Not sure, if i held Space key, but i thought they just threw me in water into shark's jaws.
3. Hi score name dialog... needs fancy GUI styling.
4. Speed of the game... Not sure if it was meant this way or is it speed scaling on my particular 36 core rig, but the original ran at somewhat slower pace. My scuba diver moves hillariously fast, so does the boat above.
Otherwise, this is very nice and long-awaited remake, congrats!
