My Journey with ‘The Left Hand Isaac’
Okay, so I wanted to talk about this thing I started doing a while back, which I kinda just call ‘the left hand isaac’. It sounds weird, I know. It started pretty randomly. I had some extra time on my hands, you know how it is, maybe a bit bored, looking for a different kind of challenge.

I play a fair bit of games, and The Binding of Isaac is one I keep coming back to. One day, I just thought, what if I tried playing it almost entirely with my left hand? Not because I had to, like an injury or anything, just… because. Seemed like a dumb, pointless challenge, which is exactly why I guess I went for it.
Getting Started – The Awkward Phase
Man, it was rough at first. Like, really clumsy. My left hand usually just sits there on WASD or whatever, doing basic movement. Suddenly asking it to handle movement and shooting? Forget about items or bombs for a minute. Just moving and shooting felt like trying to pat my head and rub my stomach while riding a unicycle.
- I kept bumping into walls.
- Missed shots by a mile.
- Died. A lot. On the first floor, even.
- My brain just couldn’t coordinate it properly. It felt like my hand belonged to someone else.
I spent a good few hours just fumbling around. Honestly thought about quitting maybe five times in the first session. It wasn’t fun, not in the traditional sense. It was frustrating. But there was this tiny stubborn part of me that wanted to see if I could actually make it work.
Figuring Things Out
So, I didn’t give up. Instead, I started messing with the controls. That was key. The default setup just wasn’t cutting it for this weird experiment.

I remapped almost everything. Put movement on the arrow keys, which felt super unnatural at first since my right hand usually lives there. Then I tried mapping the shooting directions to keys around the WASD area, like TFGH or something. It took a lot of trial and error.
Practice, Practice, Practice
Then came the grind. Just playing run after run, forcing myself to stick with the left-hand controls. It was slow progress.
- First, I focused just on moving smoothly without constantly crashing into rocks.
- Then, I practiced just shooting, standing still, trying to hit stationary enemies.
- Slowly, I started combining them. Moving and shooting. Still died a lot, but maybe on the second floor now! Progress!
- Using items and bombs with the left hand was the next hurdle. More key remapping, more awkward fumbling.
It probably took a solid week or two before it started feeling even remotely natural. My left hand actually started to feel… smarter? More coordinated, anyway. It stopped feeling like a dead fish hanging off my arm.
Where I’m At Now
Now? Well, I can actually play the game pretty decently like this. I’m not setting any speedrun records, don’t get me wrong. I’m definitely still better playing normally. But I can complete runs, beat bosses, and it doesn’t feel like a total uphill battle anymore.

It’s kinda cool, actually. It feels like I unlocked some weird achievement in real life. It taught me a bit about patience, I guess. And how adaptable we can be, even with something as silly as playing a video game with the ‘wrong’ hand. It’s just a small thing, this ‘left hand isaac’ experiment, but it was my little mountain to climb for a while. Gave my brain something different to chew on.
