A hack of my favorite section of cactus’ game Psychomnium (a convenient Flash port of the original game can be played here). I simply isolated the “bee” section, made it scroll, added a second checkpoint, and added a second bee. It’s extremely difficult, not impossible, super satisfying upon completion, and a perfect illustration of “masocore” design. Piano players might get a kick out of its requirement for two-handed dexterity.
