v1.2.1

-Added Rear Gun Scale for one-player Arcade modes, letting extra lives power up the rear gun too
-Added Unused Sprites, on by default, giving 21 weapons and sidekicks distinct shop icons
-Reworked Endless mode forgiveness; it's now split into Relaxed, Standard and Hardcore modes
-Reworked the Run Over screen with lifetime cash earned and spent, separate records for each run mode and new milestone messages
-Endless records now show a trailing C when a custom weapon flew the run, as in Furthest zone: 58 C
-The Endless seed screen now shows the selected mode's zone record, and High Scores gained a final Endless page listing every mode and its records by difficulty, each erasable behind a confirmation
-Opening Salvo now carries its boost into delayed secondary explosions from weapons such as Mega Pulse and bomb sidekicks
-Improved crash and rollback-netcode troubleshooting with clearer reports and timestamped per-session logs in a dedicated log folder, so older reports are no longer overwritten
-FluidSynth now finds SoundFonts beside the game as well as in the data folder, and is unavailable when no SoundFont is present
-Fixed the Endless E-Shop unexpectedly refreshing when moving between the Episode 1-3 and Episode 4-5 weapon sets
