do not let your left hand know

do not let your left hand know is a horror single-choice game made in Twine, in which two women, Monica in 2017 and Lisa in 2024, struggle to keep hold of their bodies, something tries to take over. The game switches back and forth between the two as they are faced with revelations. This body and psychological horror story has two endings, through that final and only choice.

The game has an interesting discussion about identities, the persona we choose (or are forced) to bring forward in any given situation, and our relationships with our bodies. Monica feels like she is borrowing her body while travelling, as if pretending to be someone else and experience their life (want for happiness?). Lisa has a stable but boring life, but finds herself missing days on end, unable to remember things that she may have (not) done - like blanking at her desk for three days. Both harbour feelings that their body is not quite theirs, that it has somehow a mind of its own. As is, it makes for quite the distressing tale...

... but when it is revealed that (Spoiler - click to show)Lisa and Monica are just different sides of the same coin, that's when the horror really sinks in. Who was there first, really? Or (Spoiler - click to show)did they enter the body, like some parasite? or maybe even split following some trauma as some sort of response? Are there maybe more identities that neither Monica nor Lisa acknowledge? And who is actually in control, after all? technically you...
But the game doesn't care much in answering these questions, and is, instead, more interested in who should be in control of this body? This is what you are faced with at the end of the game, to choose between (Spoiler - click to show)Lisa with her boring life and unassuming personality, which makes her so forgettable that she'd spend three full days being catatonic before someone notices OR the social Monica who forged relationships in the past, made connections which brought her heart pumping. It's just one or the other. The left or the right hand. Whose side will you take?

While this is a powerful choice on its own, especially with the build-up of the previous passages, getting more and more distressing and gruesome, the game also makes it way to easy to impede on the significance of this choice. The interface lets you UNDO that choice with just a click on the bottom arrow (or save at the choice, then reload). And it doesn't make that final choice feel final.

I also struggled a bit with the formatting of the text. Mainly with the alignment of the text not always being contrasted enough between the left right and centre blocks (especially with long sentences/paragraphs) - smaller width would help section those blocks better. As well, a bit with the dialogue/thoughts lines, I wasn't always sure who was talking or whether it was inner thoughts (until the context kicked in, but it took me out of the immersion a few times).

Overall, a cool piece of horror, with a great sense of mystery and build-up.
