I have two control keys! They're under D and K, through the miracle of mod-tap. Look into home row mods, it's a game changer. Here's my keymap for reference — it's a bit of a work in progress, I keep finding little things to tweak or improve.
As it stands, the two outer thumbs (App/Alt) aren't even mapped at the moment, they're too tucky for my hands, and the outer row on the left isn't exactly what the cap legends say, either.
Why not make a "game" layer that doesn't get in your game-playing way, and have mod-taps on the rest? (as far as they don't interfere with the chords, of course)
Yes, but it depends really on what you want to bind where.
In my case, I have no capslock and I have ESC, TAB, shift, ctlr (on the outermost column) and alt, super, lower, space (on the bottom row/thumb. Obviously with qmk (or similar) you can change what you want, but I assumed it was pretty standard layout (in fact, I changed very little from stock keymaps in qmk).
Oh I see what you mean, control in the leftmost place in the bottom row. Yeah, that's not possible. I don't use the lily58 to play the games where I have years of muscle memory to be honest.
