Ninja

The ninja wields a katana that makes them go very fast! Later, they're able to gain walkspeed sustainably, and convert that walkspeed into HP when needed!

[0/6] Hasten - Gain 1 walkspeed. You may also use this in a special room to get 2 walkspeed.

[0/1] Meditate - Lose 1 walkspeed. Then, gain HP equal to your walkspeed. Only useable in special rooms.

This is the only class to start with a debuff as of 1.1. Although this debuff is countered by the fact it starts with a katana and can steadily gain speed throughout the run.
