These are all of the difficult+ Chips currently in the game. Most if not all of these feature a minigame, puzzle, or confusing task. Also mini rant, don't be blinded by games with collectibles with crazy good designs being the hardest ones. I find a design I like, find an idea for it, and implement it. Wasting time on gradient slop does nothing but make your game inconsistent and feel no different from the rest. Alien Chip has THE most basic design of all time yet is the hardest Chip, a decent design and fun gameplay is far better than a sloppy design.
