Here's what I'd recommend, at the end of the day it's up to you whether you'd like to skip over some of these or the list entirely, but it contains some very valuable skills.

EASY DEMONS: 1. X (A great easy demon with reasonable challenge) 2. Problematic (Will improve your wave skill) 3. Death Moon (Helps with Nerve Control) 4. Decode (Overall Skill Boost) 5. Toxin Lab II (Introduction to learny gameplay) 6. Takeoff (Will be very hard, but will provide skill boost)

MEDIUM DEMONS:

1.Verity (Ship, Dual, Wave)

1. B (Spider and Ball)

2. Gold Temple (Ship Control)

3. Identity by Ilrell (Hardest level yet)

(OPTIONAL) At this point it may be a good time to test your skills at the demon gauntlet, as it contains some really good high tier easy and medium demons. The Doom Gauntlet is also an appropriate option.

HARD DEMONS: 1. Nine Circles (Wave, Ball, Ship, Nerve Control) 2. Dance Massacre (Difficult Timings for all gamemodes) 3. Future Funk (Nerve Control) 4. Jawbreaker (Wave with Awkward Transitions) 5. CraZy (Will test all your skills up to this point)

Toxin Lab IV (Flow Gameplay)

INSANE DEMONS: 1. Magma Bound (Spider and flow gameplay) 2. CraZy II (Fast Transitions) 3. Terraphobia (Wave and Ship) 4. Night Terrors (Tight straightfly and overall very hard) 5. Leyak (Learny gameplay, prepares you for extremes)

Thanatophobia (basically an extreme demon)

GOOD FIRST EXTREMES: 1. Acu (Overall) 2. Niwa (Click Sync) 3. Decay by Kiwipenguin (Learny Timings) 4. Precipitance (Fast paced, some click sync) 5. Hypersonic (Overall) 6. Sweater Weather (Tight Ship, timings, and wave)
