Nightmare Mode

Nightmare Mode is Jetshift's form of an Expert mode. It offers a load of challenges to players who find Normal Mode way too easy, such as dodging more attacks, making some bullet hell situations and even giving enemies more health. So far, the only levels that can be played on Nightmare Mode are boss battles and during Arising Giants. Sidescrolling levels are unaffected, as the only difficulty available for sidescrollers is only Normal.

Changes

 * Bosses have more health, and it increases further for every level of Strength the player has.
 * Bosses will fire more attacks rapidly, allowing for situations where the player could get trapped and have no way out of attacks.
 * Some phases will be skipped, and occasionally clash with other ones, allowing for new attack sequences.

Harder Mode?
The creator of the game, Lawrence, had an idea one day that he would make a mode that is significantly harder than Nightmare, called Hell. It would be played in such a way where bosses have ten times as much health than in Nightmare and does even more attack summons, the player only has 1 HP and failing the level will result in losing most of the in-game currency that the player currently had before. He stated;

'' 'I find it hard enough to work on one mode, let alone two. The idea of making three is just a 'Nightmare' and even if I could get the time to do difficulty after difficulty, I wouldn't do it. Too much work and stress.'''

It is unknown whether or not in future updates of the game there will be such a mode, as this was made for his final major at college during Digital Arts.
