This update includes some quality-of-life improvements suggested by players, some fixes for issues which came up during the Steam Deck compatibility review, and many general engine improvements.

added alternative render style unlock, to enable pixel shading, retro shading, sepia shading, or overdraw mode
added per-area leaderboards for classic mode (already filled with real data)
added badge and trophy descriptions to the pause menu
added a new option to configure game brightness
changed screen-shake effect to actually shake the GUI instead of the game, but the old behavior can be restored by setting the screen-shake option to a negative value
fixed game running too slow when playing with forced vsync or with a framerate limiter (like on Steam Deck)
fixed rain drops on water not working on some graphics drivers
fixed not being able to change the game resolution on Steam Deck and Gamescope
improved high DPI support for Linux and macOS
improved gamepad hot-plugging behavior for co-op mode
improved overall performance
The game now also includes various alternative render styles as can be seen in the screenshots below. They can be unlocked by beating the true last boss or with the password UMBER.
Creating the update took a bit of time, as I kept finding new issues during testing which I wanted to fix before the release. If you find any bugs, please don't hesitate to let me know.
Thank you and have fun! 🙂

Happy New Year!
It took a bit of time, but the new update is finally here. It introduces a ton of new features, improvements, fixes and a replay system.

added replay system
added jukebox unlock
added new achievements
added rapid fire toggle button for twin-stick and mixed control mode
added a new option to configure water quality
added a new option to configure particle effects
added the missing amount of time for the next higher medal to the time-bonus screen
added a hard alternative way to fight the true last boss without collecting all the fragments (1CC without shield)
changed game speed to only affect actual gameplay situations (not transitions, summaries, or other events) to prevent timing and audio issues
changed keyboard movement keys to cancel each other out instead of prioritizing one direction per axis
fixed an issue where enemies would sometimes be attackable while not on screen
fixed best time on the classic summary screen displaying an incorrect value for a full play-through
fixed incorrect mission medal calculation for area 8
fixed rapid fire not working as intended when using certain temporary weapons
fixed occasional vegetation popping artifacts in the background
improved boss health clarity by splitting the health-bar into different phases to highlight important transitions (where it is possible and makes sense)
improved stability and performance when playing at any game speed other than 100% or any update frequency other than 60 Hz
improved overall gameplay precision, timing and determinism
improved overall gamepad menu navigation
many other improvements and fixes
Eigengrau now supports Replay recording and playback for Classic Mode. Replays are automatically recorded and can be saved and organized locally. They are also uploaded to the Classic Mode leaderboard for others to download, watch and verify (if available).
Full play-through replays have been successfully tested across AMD, Intel and Apple Silicon CPUs, across Windows, Linux and macOS, and under various other conditions. If you still find issues, please let me know in the community forum and I will try to address them.
The game now also features a Jukebox, as many players wanted to re-listen to certain tracks later in the game. It can be unlocked after hearing every available music track at least once or with the password ISABELLINE.
A couple of new general Steam Achievements have also been added. It should be enough to load-up a compatible save-game to unlock them, if you already fulfilled the requirements.
Thank you and have fun!
