Character info:

Passive: Energy Conversion
Finitevus cannot acquire shields. Shields instantly converted into rings (amount depends on type of shield).
However he losses only 25 rings on each hit, but those rings will be lost for good.
You die if you get hit with less than 25 rings in possession.
Finitevus always starts stage with additional 25 rings (meaning boss stages start out with 35 rings).

Controls:

Jump Ability: Warp Ring. Hold jump in air to aim, release it to create a ring portal between two locations if location is valid.
Pair of placed warp rings lasts for 1 minute. 

If direction button held - you create ring in front of you, which leads to another created further, and slightly recoil back.
If no direction button held - you create ring bellow you, but second ring will be created at close range and you recoil upward,
however it'll ignore height check and try to spawn to closest height, which allows you to get on higher places or underground.

Pressing Next\Prev weapon (mouse scroll)
During Warp Ring aim - change distance between rings.
Everything else - change gravity settings for newly placed rings.

Jump+Spin: After a short delay you propel up and spin around.

Pressing Spin again switches into glide. Compared to Knuckles you don't need to hold a button for gliding.
This gliding technique doesn't reduce falling much (falling at constant speed of 10 fracunits) but makes it up with speed and instant camera-controlled turn (its also possible to steer a little with strafe buttons).
Its objectively better over long distances than simply falling.
You can speed up transition into glide by holding Spin button skipping propel. You can cancel gliding by pressing jump.

Can be used after creating warp ring midair but not other way around.

You cannot glide underwater but propel have much more height instead, however you can switch into glide if you emerge from water after propel.

Spin: 
Charge dark chaos energy.
If pressed or not charged - throw Thunder bolts at short range. Thunder bolts pierce walls

When fully charged (1 sec if you have 5 rings, 5 seconds if you have less)
Release a Chaos Bolt which tracks closest enemies and monitors, jumping between em up to 4 times.

Custom 1:
Warp back to spawn or last checkpoint. Costs 10 rings. Can be used midair but cannot be used when performing any of other abilities (warp\glide).

Tossflag (when standing still):
Recall all warp rings. You gain ~75% from each pair of warp ring time left as charge.
