Ignoring the first launch launcher issue, the game is fully playable without a single issue.

Can only change the resolution on the main launcher. Obligatory on first time launching the game.
Steam does not support Cloud Saving for this game
-q as a command should ignore the launcher

Audio is mixed weirdly, meaning some music and voice lines start too early. Unsure if this is just a Linux thing or an issue with the remaster itself.

Game runs perfectly fine, but you need to set the player 1 input device to gamepad in the launcher
Have to change input in launcher on first start up

you have to use the touchpad to configure the launcher when starting the game for the first time
runs well and couldnt find any issues or bugs, use touchpad to configure launcher.

CPU 6 watts GPU halved
No Steam Cloud which can be annoying
Will need to use Steam button + Touchpad to configure in the launcher when the game initially starts.
Had to change to gamepad layout in the launcher. Had to restart the first time as it wasn't detected originally for some reason.
Annoying launcher requires changing to gamepad mode and using the touch screen but once launched the game is fine.
Game works well out-of-the-box. Installing mod loader breaks stock Launcher, but this issue can be solved.
Installed mod loader, renamed original Launcher.exe, symlinked sonic2app.exe to Launcher.exe
Out-of-the-box, the game has a launcher for configuration which must be operated with the touch screen. This can be mitigated by renaming or deleting Launcher.exe and symlinking sonic2app.exe to Launcher.exe.
The game works perfectly out-of-the-box, I didn't notice any issues. I installed the mod loader and am using it through Bottles, and the stock Launcher ended up breaking in Steam, with an error that showed up anytime I clicked the play button. To fix this, I renamed the stock Launcher and symlinked sonic2app.exe to Launcher.exe. The mod loader can perform all the actions of the stock Launcher and more, so no functionality is lost. This probably isn't the cleanest solution and may break in the unlikely event this game is updated in the future, but it works and is easy to redo.

Minor UI/menu bugs when resolution is at a 16:10 ratio
Vanilla seems to be fine. Modded works better with GEProton and the above launch options. Minor bugs at 16:10, though nothing that would significantly harm the experience. 1280x720 is flawless. The mods I could not get to work were HD GUI and Chao Data Menu, all my other mods functioned just fine.
