Update on February 19th 2025: a revision 1.45.0.5 has been uploaded to remove beta tag from the game.

This major patch, dedicated to Randamu's third anniversary on doukutsu.club and itch.io, adds ability to add custom characters, customize item and NPC properties and reworks JSON patching with resource overloads, adds a new summon item, revamps the tutorial aspect of the game, majorly buffs Frontier Buster and Energy Flail, adds new boss songs for Reinforced difficulty, updates some visuals and fixes a lot of gameplay and stability issues.

Go to Randamu forums if you want to discuss things in new update!

Highlights:

• Added new item, Remote Controller:
  • this item summons unique Boosterama, a robotic Prof. Booster that hunts enemies around you
  • Boosterama shoots enemies with unique Booster-themed projectiles, that explode on contact with terrain or enemies
  • Excerpt gets Boosterama as innate
• Reworked Fragile gimmick:
  • now sometimes causes chain reactions during breaking blocks
  • some blocks during chain reaction may turn into rubble entites, that damage you on falling
  • this can currently cause infinite loops in some scenarios
• Made flag-specific game logic data-driven:
  • the tag file is `flagTraits.json`
  • this tag contains associative array with flags as keys and lists of traits as values
  • traits define, what should happen or what should be possible, when this flag is active
  • this is basically EC (entity-component) system, but with flags
  • every trait and its parameters are described in new documentation page: https://doukutsurandamu.github.io/namespace_flag_traits.html
  • there is a lot of possible regressions and inconsistencies connected to this big refactor, so make sure to report all of them
• Added data-driven custom playable characters:
  • every character is defined in its own folder, that includes definition JSON and character's spritesheet
  • character definition's parameters are described in new documentation: https://doukutsurandamu.github.io/struct_m_y_c_h_a_r___d_e_f_i_n_i_t_i_o_n.html
  • character order can be defined with `order.txt`, with possibility of automatic arrangement
  • many character-specific properties and quirks are defined with new flag trait system
  • <MIM command is removed due to no longer being needed
  • character select screen descriptions have been transferred from `StageSelect` script to character definitions
  • removed `characterNames` tag due no longer being needed
• Revamped JSON patching:
  • replacing JSON tags directly now works as with other files, removing `override` functionality
  • the patches instead are grabbed from `Changes` folder in each resource pack
  • patches are applied in alphabetical order and can have a priority to load before other patches
  • patches can be either JSON Patch or JSON Merge Patch format
• Unified occassional NPC properties tags into data-driven NPC traits:
  • `aquaticEntities`, `bonkableEnemies`, `bossNPCs`, `etherealEntities`, `knockbackImmune`, `lifeIncreaseImmune`, `lifestealEntities` and `timeStopCoefficients` tags have been removed as a result
  • NPC traits are also reloaded during every config full reload instead of NPC table loading phase
  • the format is the same as flag traits: NPC IDs as keys and their traits as values
  • the documentation is yet to be done :tm:
• Added `equipVisuals` tag:
  • this tag defines the order of overworld-visible equips and with what flag they should be visible
  • `accs_id` refers to members of grid on MyAccs spritesheet
• Added 2 new random stage music tracks.
• Added Reinforced difficulty replacements for second campaign's boss theme and Doctor's boss themes.
