Spoilers

I am at the final scene at the nuclear reactor core. Fay cannot move after giving the algae to Salvador.

This normally wouldn't be a problem because I am really good at saving, but I am on my Continue because saving stopped working a couple chapters ago!!

It's the same for me but a little earlier. After opening the beer at the jungle bar bent bounces on an invisible wall when trying to leave the table.

OK, these last two are solvable. Lay some keys back on the table, then you can move again.

I suppose the devs wanted Bent not to leave because the Guard wouldn't let him go with the keys. But you can bypass that by double-clicking on the far-right exit (the screen must shift to the right before).

No idea about the nuclear reactor core though.
