Works fine without any adjustments
I've sunk days into the old flash versions and I'm going to do it again…
Works flawlessly on Proton

Right clicking to target gems unfocuses the window, forcing to alt tab out and back in. A workaround for this is running the game in windowed as opposed to fullscreen, which fixes it completely.
Shift tabbing to open and close the steam overlay crashes the game. Have a seperate steam window open instead of shift tabbing.

The right click to target bug that refocuses the window can be solved by forcing experimental.
Game works perfect out of the box besides the mouse bug, some tinkering with the graphics settings may be necessary to get consistent fps depending on the amount of enemies on screen.

Works fine
After right click the game loses focus and ignores mouse clicks, changing window focus back and forth fixes it. Not the end of the world.

very small text
black bar at the top cuts off the config button
touch des not work for combining gems and a few others, touchpad has to be manually configued tp reach the bhole sceen whie dragging
game crash reboots steamdeck when opening the steam overlay
Runs great. Only issue is game crashing if you open and close the in-game Steam overlay (which is avoidable)
Good experience.
Right-clicking makes the game stop receiving input.
Works perfectly fine.

Se cuelga al usar el botĂłn derecho del ratĂłn casi a la primera.
Algunas funciones del ratĂłn, sobre todo del botĂłn derecho congelan el juego.

Under bspwm, game does not respond to mouse input after a couple minutes. No issues under a normal desktop environment though.
Using bspwm, mouse input is not recognized after a couple minutes.

Required tinkering to get rid of audio crackling. Encountered a few mouse input issues during gameplay. Game runs smoothly on intel GPU.
Audio crackling went away after setting tsched_buffer_size=0
and PULSE_LATENCY_MSEC=90

After pressing right mouse button, the game sometimes seemed to have lost focus and further mouse clicks were ignored before I switched to another workspace and then back.

Everything works out of the box except for the Steam Overlay
Steam overlay did not work

Works out of the box with no issues. 4k resolution gets very laggy, but I can't really complain because officially the game only supports up to 1080p resolutions. I resolved audio cracking with PULSE_LATENCY_MSEC=30 %command%
, but I believe this is specific to my setup and not a general issue with the game.
This is basically a Flash game + a Flash player in exe (with aux stuff such steam achievements support), so you can also play it using a native Flash player too.

I have played only for a hour and what I can say is except problems with focus after right-click, everything is working fine.

Problem with losing focus after right-click is still existing. Also shift-click + drag to change gem focus is not working for me.
