As a bonus, since I looked at all the `on_draw`s, why not look at all of the `on_tick`s?  It's useful knowledge to know the order in which things occur:

             `this` | Priority | Address    | Notes
                ===  | === | === |===
 **`0x4c10d0`**      | `0x01`   | `0x43b3d0` | Reads raw keyboard input.  Supervises threads?  Does D3D... stuff.
 **`Thread63c`**     | `0x03`   | `0x43b290` | Checks the configured game resolution and... lolidunno
 **`AsciiManager`**  | `0x04`   | `0x408070` | Simply ticks down `remaining_time` (`+0x12c`) fields on strings and deletes expired ones.
 **`MainMenuThread`** | `0x06`  | `0x44af80` | Allows navigating the main menu.
 **`AnmManager`**    | `0x09`   | `0x46e710` | This is `on_tick__ui`.  It advances ANM VMs in layers 36 to 42 and rebuilds their layer lists.
 **`Global3f4`**     | `0x0a`   | `0x43e3f0` | Related to the Pause menu.
 **`HelpManual`**    | `0x0b`   | `0x401300` | Responds to keyboard input while the help menu is open.
 **`ThreadB4`**      | `0x0f`   | `0x42db70` | I think this object is the main game thread, but it doesn't have much work to do thanks to everything else.
 **`Global31c`**     | `0x10`   | `0x448e30` or <br/> `0x447fd0` | Input related.  
 **`Stage`**         | `0x11`   | `0x40a7a0` | Plays STD script, does... things!  Things it does!
 **`Unknown40`**     | `0x13`   |  Various   | Numerous things create these objects, such as ECL `screenShake`, and they have different `on_tick`s.
 **`AsciiPopups`**   | `0x14`   | `0x449ea0` | Updates those tiny little score, PIV, power and graze popup texts written in kanji numerals.
 **`Player`**        | `0x16`   | `0x442560` | **HUGE.** Watches input, moves, initiates bombs, shoots, moves player bullets, precomputes hurtbox...
 **`ShotType`**      | `0x18`   | `0x40da60` | Character.  Runs per-tick logic of a bomb if the player is using one.
 **`ShotType`**      | `0x19`   | `0x40da60` | Subseason.  Same but for releases.
 **`EnemyManager`**  | `0x1a`   | `0x41af44` | For each enemy, runs ECL, takes damage from the Player, maybe kills the player, and lots, lots more.
 **`LaserManager`**  | `0x1b`   | `0x431330` | Runs game logic for each laser, similar to bullets.
 **`BulletManager`** | `0x1c`   | `0x412c50` | Moves enemy bullets.  Check graze conditions, maybe kill the player.
 **`ItemManager`**   | `0x1d`   | `0x4308f0` | Moves items, checks for PoC/autocollect/attraction/pickup, performs item pickup effects.
 **`Spellcard`**     | `0x1e`   | `0x417ee0` | Messes with anms, updates spell bonus, checks for bomb usage.
 **`Global2020`**    | `0x1f`   | `0x418ab0` | Scans an array of anm ids at `this+0x1c` and replaces them with `0` if the ANM VMs cannot be found. found.
 **`Gui`**           | `0x20`   | `0x429af0` | Extremely involved.
 **`AnmManager`**    | `0x21`   | `0x46e710` | This is `on_tick__ui`.  It advances ANM VMs in layers 0 to 41 and rebuilds their layer lists.
 **`Global31c`**     | `0x22`   | `0x448e40` | This code has no side-effects.  Strange.
 **`Global24`**      | `0x23`   | `0x4196c0` | Somewhat involved. I think this object might represent the Ending?

TH17 is sure to have some differences.  (for instance, TH17 has no subseason ShotType, but it has a TokenManager, so some ids are surely shifted).
