Works out of the box. I used Proton 7.0-5 Flatpak community build.
When starting the game for the first time in fullscreen, only 1/4 of the game will be displayed. Changing the resolution in the game's .ini fixes this:
- Proceed to ./steamapps/common/Hitogata Happa/“ and open “happa.ini” in a text editor. Modify to “Resize=-1”, along with “Width” and “Height” to your native resolution.

Started with the screen rotated 90 degrees. Changing rotation in the settings caused menu options to be cut off the bottom of the screen, but after restarting the game everything seems to stay scaled and positioned properly. Runs well after that. Tested with a PS3 controller.

Launches in a cropped overlay despite being in full-screen mode. Have to press Up, Up, Z to reach the options, at which point switching to windowed mode then back to full-screen mode resolves the issue until the game is next launched.
