It's gonna be a bit tough. Quite a lot of the animations are so deeply baked into the core of the game. But could add options for removing some easy stuff like bg, clouds etc which would already help some I think. I'll see what I can do. Not probably going to happen on the next patch (coming maybe later today or at least in few days time) yet though.
Thank you for taking time for this!
The main issues are the camera wobbling/zoom in and out (which makes it hard to select the right cargo), and the background/animation (removing them could achieve better performance).
I also thought that an option to rotate the game window might be useful, as the camera zoom would probably be lessened (since the display would be full screen, so bigger), but that might require too deep modifications to be easily done.
As for feedback, I feel like the obscure game mechanics add replayability and complexity. However I dislike the "non-useful" encounters that simply makes you skip to the next fight (i.e. meeting the seafolk ship without having met the requirements...). Otherwise pretty much all aspects of this game are wonderful, the dices and the number 13 are extremely well incorporated in the game theme and mechanics...
Thanks again!
