I rate this the highest possible before comments turn into spam, i.e. four stars; my only complaints [about steam and discord] have been posted in a separate thread, this one should remain about the game itself.

I played almost entirely via touchscreen, and did not test any keyboard features; the gameplay does not seem to require them. Most mechanics were either self-explanatory [required little reading and no significant cognitive load] or had sufficiently accurate descriptions that I blamed bad fortune for my losses, rather than myself.
