ah I see, I honestly felt the unlock order was perfect, slightly increasing the complexity each time, I was definitely hooked, maybe I would keep it this way, then again I don't know what else you have in store!
I am playing on browser maybe that's why, the save is simply not there and I have to restart from scratch, not a big deal anyway, just fyi. (Firefox)
Esc and controller support would be amazing, but don't rush on it, i spent way too much time making controller work haha. Though it would play very nice on a steamdeck!
