This is the pure-speedrun achievement.
Specifically, you must:
-Beat the game in UNDER 2 hours
-NOT have collected every item; as long as you are missing at least one of any the following tracked items you are good:
+17 Magic Jams
+3 Heart Holders
+Any of the 9 Spells, 4 Upgrades, and/or the Map in the Store
HOWEVER, to finish the game you are required to at least obtain any one Fire element spell (to unlock Monkey Bullet).
Note: If you are playing in Magic Mode, then all magic will be even more useful as they can be used more, though at the cost of taking double damage.
