Okay, 3 things I would change on here for anyone who plays on here in the future:
1. Prevent magic and foil items from going into the collection collector by default. Once you have so many items it's hard to keep track, and you can't see what items go into it when you have just the singular button to click. i.e. Magic and foil items should not count as part of the sets.
2.
Also in the collection collector, having an accessible list of items in each set would be pretty nice. I find myself checking old forum posts from 10+ years ago that have lists arranged but having it all in one place would be nice.
3.
Broken Games that either don't submit scores or don't work at all that I know of:
Snake (3D version, submission error)
Box of Chocolates (Submission error)
Kangaroo Jack (Submission error)
Minotaur (Submission error)
Word Pads (Unplayable)
Mouse Maze (Breaks at level 5)
Frogger (Submission error)
Freakshow Pinball (Submission error)
Asteroids (Submission error)
Games that have a white screen but work when you right click and hit play (like Beat Bubbles):
Jungle Monkeys
Power Arrow
