I don't suppose there's any hope of a 32-bit version being released? I'm not very technical so I'm not sure if this is even possible, but thought I would ask. I put in my steam key only to discover I could not install it because it is 64-bit.

We'll try to ask PyTom about this, when we first used renpy, we could use both in 32 and 64 but in the latest renpy (which is required to make it work on steam) it only had 64 settings. We'll ask him about this details as well, since we're not that expert on ren'py either so sorry!
