Cool idea, but the control scheme really needs some work. io for ability/interaction as well as jkl for character switching is all just kinda janky. So was the strange controls when holding an object as the strong robot. Definitely a neat idea, but needs polish.
Its had to say, but I would've personally bound the ability/interaction keys to q and e. Though thinking about the bot switching, it may make more sense to make q and e cycle between bots, and have f and r be interaction / ability or something. I have also considered having only one button (like c) to cycle the bots, freeing up the f, e, and q keys to be whatever you want. But I really don't know for sure. Plus, it depends what you want the other hand to be doing, as I dont recall needing the mouse in this game for anything other than menuing. Hopefully someone else with more experience in game dev can provide more insight into this than I can haha
