- Mirror Mode: Get the Bancal Mirror on level 97.1

; in that mode the levels are mirrored (left/right side reversed), but Igor moves as always.
- Nightmare Mode: Get

after beating Tuber; everything is a bit faster (Igor, the fruits and the fireball)
- Ninjutsu Mode: Get

(level 23.6), then finish the "Shinobi Do!" quest. In this playing mode you have to kill one certain enemy to end a level; when you hit one of two certain other enemies, you lose a life.
- Tornado Mode: Finish the "Best Player" quest (collect all the gamepads). Igor starts the game with a speed boost.
- Unstable Explosives: Get the red bomb far down in Hell. Igor's bombs hit not only the fruits, but also Igor, and all explosions are bigger.
- Two Players: Finish the Sandy quest. You can play together with a friend.
- Two Players Mirror/Nightmare modes: Same as normal Mirror/Nightmare.
- Two Players "Bomb Control" mode: Unknown (as fat as I know)
- Time Attack: Get 150

(you get them in Ninjutsu Mode). It's a different game - you try to beat special levels as fast as possible.
Two Players and Time Attack are the games you can unblock ("To be unblocked" on the left); the other ones are additional game modes after you have chosen to play Normal, Two Players or Time Attack.
