Changelog

v.20260301

• This is a small bugfix release:
  • Fixes a bug in tilemask loading, which broke some levels, since some tiles were not passable (e.g. in Medivo)
  • Fixes a bug in palette handling when using SDL3 and no scaling, leading to wrong colors
• New features:
  • Most menu screens have now centered output and are better aligned on small displays (original resolution of Jazz is 320x199)
  • The HUD can now be changed to be like in FPS games (e.g. DOOM1, quake...)
  • Jazz' and enemy health is now affected by the difficulty level, which means the game got a lot harder on higher difficulty now
