Version 1.21 Released! Now with TV-like filter!

1.21 is here! This update takes care of a few issues, mainly in Panic Puppet Zone, and introduces a new TV-like filter for your viewing pleasure!

- Added a new TV-like composite cable filter! By pressing F5 you can now toggle between 3 different filtering options for the game. The first option is a tv-like filter that slightly blurs nearby pixel horizontally in a comparable way to what old TVs did. The second one blurs only the background to exploit the background dither effect, but keeps the playing field nice and sharp. The third option is no filter at all, like it's always been. Your current filter setting will be saved whenever the game is normally saved.

You can see the filter in action in the picture below. Pick your favourite setting!

- Updated layering for all the screens in the game to account for the new TV filter options

- Adjusted 1 misaligned animation frame for Sonic and Ashura in the Special Stages
- The game wrapper that controls the pause has been optimized by removing unneeded objects
- Added a new routine to force silence on music tracks. This should finally make the Special Stage music end when a Chaos Emerald is obtained.

- Added a missing end-floor tile in Panic Puppet Zone Act1.
- Fixed Wechnia, Tails, Sonic and Ashura's animation speed at the end of Panic Puppet 1's cutscene when they appear as NPCs
- Added a spring in an underwater area of Panic Puppet Zone 2 where Sonic and Ashura could get stuck after getting an extra life. While I always considered it difficult for Sonic and Ashura to access it and the extra life would compensate for the forced death, in the end it's useless to burden a player with a Mystic Cave zone pit, even if it gives you a life back.
- Added a control so that if the player is in a hurt state it will never hold on to a hook in Panic Puppet Zone.

Special thanks to MikeSonicYT for reporting the following Bugs:
- Fixed an animation bug with Amy when transformed during the Panic Puppet1 Zone Boss where her flight animation wasn't triggered.
- Fixed a bug at the start of the cutscene for Panic Puppet 1 boss that would lock Knuckles's controls into a glide action instead of resetting button input.
- Added two missing background activators for two Starpost in Panic Puppet Zone Act 2. The internal background is now correctly loaded if a character restarts from those specific starposts.
