If your frame rate is dropping in the gunpla builder, it's likely just because of how many builders parts you put on. For some reason builders parts just really bog down the game? This occurs on Windows as well, and haven't tested myself, but apparently the Switch version too.
R.I.P Gundam Breaker Mobile. We still miss you : (

Game worked perfect, multiplayer no issues.
Only issue is game design choices.. like how players on screen are not synced, so major online desync regardless of platform.

Game launches fine with Proton Experimental. Mutliplayer works well. No compatibility issues encountered.

Runs at a solid 60fps, lowering a couple graphics options gives me about 2 1/2 hours of battery life on a full charge.
Lowered some graphics settings to medium to improve battery life somewhat.
Text is a tad small, no in game option to enlarge.
May be able to lower texture quality to improve battery life further. May be able to lower resolution to 720p to increase battery life as well, but that would require editing the ini file. Runs at native 800p resolution 60fps with no issues, so I'm happy overall.
Lots of small text. No in-game text scaling.
Works perfect

The only tinkering I did was set refresh rate to 40 for battery life. I get an estimated 4 hours on the OLED at 40
40 FPS lock
Most menus have fairly small text. nothing a set of squints won't fix

go nuts!! have fun!! haven't tested multiplayer, i've heard there are a couple issues, but i imagine they'll be fixed in the coming days / weeks.

Changed refresh rate to 40hz

Runs great, a few minor frame drops but they may be flukes, and have been rarer after turning down the graphics a bit.
Kept graphics on medium (and post-processing as low by preference) and FPS capped to 60.
Runs good, cloud save works, overall a good time! It is new, so there may be issues in the future, but so far it is fully functional.

It works great, and runs well, especially at lower settings. I mainly used proton just to ensure compatibility.
Set all graphics settings to medium (I put post-processing on low but I do not think there is a big difference)
The game is new, but so far it works swimmingly.

Gunpla (and Linux) is freedom!
No issues have been found. Have fun constructing your Gunplas, Steam Deck owners!
