I was wondering if controller support might be possible someday, or at least a simplification of the number of keys required to play, such as selecting items and upgrades with the directional keys and space/enter instead of abc.  Perhaps a menu screen to access character stats, inventory, powers, and so on instead of separate keybinds.

I've tried to play this on my Steam Deck as I love the idea, but as of right now it's unrealistic to manage all of the required keys, unfortunately.

This is possible, if you can help with the design I can go ahead and give it a try at implementing it :)

I think right now there are a lot of things you can do from the inventory screen that make some commands redundant, we probably just need to bundle some "system" commands in a menu.
