Playing it on the Steam Deck (OLED) as we speak. It's a golden find. Has the potential to be VoA (Verified on Arrival).
A couple of things to note though:
1. There's a weird "Windowed mode" bug whenever I switch back from fullscreen (1280x800) to windowed mode (1024x768). A chunk of the left and right side of the screen cannot be accesed with the mouse cursor unless in fullscreen (as evidenced by the white dot).
2. The fullscreen mode itself is (in my opinion) poorly aliased on a 16:10 800p screen using some kind of NNI (Nearest Neighbour Interpolation) variant. Could be just an overlooked and/or intentional detail, but worth noting anyway.
3. The game is strictly mouse only. I'm not saying "controller support" right away, but it can't even be navigated with a keyboard. Mapping a custom bind configuration in Steam is one thing, but the old [Arrows/ZXC] config could come in handy for the ease of use of the navigational aspects more than anything. Like pressing 1, 2 or 3 to bring up the cards right away before clicking on the snails.
But that's just me and my suggestions. It's your game. Do what you think is best. I'm just happy I can live to play it. Don't take my points as being a Picky Pete.
