Thanks for trying it out!
Concerning keyboard layouts, I've haven't done the work yet to automatically detect keyboard layouts but you can rebind the controls in the option menu, which I think is a good "catch all" for the moment. The game is supposed to be played with a controller anyways, so I don't think this should be too much of an issue down the line. Honestly keyboard controls are based on common gba emulator controls, since this game is based off of a gba game originally.
I'll have to look into that tab in and out issue, never seen it before.
Automatic card draw is an interesting idea. You need manual card draw though because sometimes you'll have too many cards in your hand and not enough energy to play them all, so unless you refresh your hand and energy you'd be stuck. But something to keep in mind I guess. Manual card draw also affects things that trigger each time you refresh your hand, so you do want control over that as well.
You can't rotate daemons, I thought I removed that from the tutorial. Unless it still says it in the readme? and the left arrow thing should work, another thing to look into as well.
Best tactic in the end appeared to be to just spam card usage, redrawing when the Hand is empty. and use scrap gun whenever I couldn't do anything else.
That' part of it, at least in the early game. Ideally down the line once you get better cards you'll need to understand them a bit more, and there's the whole deckbuilding part of it as well.
Once again thanks for playing!
