* Update the function signature of P_MixUp to accomodate both it and drawangle instead of doing it outside of the function.
* If the player is spawning from the start of the stage and it's from the ceiling, be in fall frames as requested (resolves#191).
* Put everything in P_DoJumpStuff, instead of half in that function and half spread across the player thinker.
* Have a proper if else cascade that first tries shield abilities, then super transformation, then random abilities like CA_TELEKINESIS.
* Use this new arrangement to allow CA_TWINSPIN users to use their ability on spin if their secondary ability is CA2_MELEE (resolves#195).
* Random bugfixing. Didn't keep track of what I'd caused while working on this and what was already there, but there was a lot of it.
The only two abilities which have spin-button properties outside of the else block is CA_AIRDRILL and CA_FLY/CA_SWIM (which now also prevents you from swimming down in goowater).
* Genesis-style love and attention to the death event.
* Only visibly decrement lives/rings when you're respawning (or game over, see below).
* Faster no-button-press respawn.
* Game Over specific love.
* Animation of Level Title font coming in from the sides.

* Change gameovertics to 10 seconds instead of 15.
* Make the minimum time before you can force going to the Continue screen longer.
* Accomodate death in MP special stages as a form of exit.
* Don't have your rings or spheres reset when you die in a special stage, so that the stage isn't softlocked with the new harder limits.
* Fix a bug with CoopLives_OnChange where changing to infinite lives didn't force a game-overed player to respawn.
Also, two not-quite death things which nonetheless were relevant to change:
* Fix quitting a special stage having some of the shared spheres/rings disappear into the aether.
* Fix a warning during compilation for the Ring Penalty print.
* If a spring has vertical speed AND horizontal speed, always set the player's angle when touching it.
* If you have less than 32 rings and spill them, they now get launched away from the player's motion, rather than in the direction of the camera.
Sea Egg is majorly changed according to Mystic's ancient instructions (excepting the flying FOF rock, I cared not for fucking around with FOFs).
Specifically:
* Faster paced fight.
* Instantly travels horizontal distance.
* Fakes no longer hurt papa, and spin out like a deflating balloon when he dies.
* New attack: When surfacing, produces an electric shockwave. Replaces underwater shock. Designed for new, shallow arena.
* Support for multiple bosses in the same map distinguished by parameter.
Will upload map to fight the new battle in on the MR.
* Remove PF_THOKKED every time a successful damage bounce occours.
* When this happens, spawn a number of particles based on thokitem at half scale! (Optimised, again, for MT_LHRT.)
* Also spawn these particles when a successful spring boost occours, as well as playing a twisted spring sound.
Also, some other related tweaks:
* Optimisations to A_VultureBlast, which was used as a base for the particle creation.
* Make the Metal Sonic boss use P_PlayerCanDamage instead of a custom, somewhat broken player damage detection mechanism.
* P_SpawnGhostMobj takes colorized into account.
* Fold Tails propeller damage into P_PlayerCanDamage.
* When performing an Attraction Blast, place the player in roll frames.
* Update all conditions preventing SH_PINK to incorporate thokitem and spinitem as well.
* Buff MT_LHRT travel distance at slow speeds.
