Not sure how people got beyond the second push puzzle, because for me it didn't recognize the second crate and kept the door locked. Sadly, because the game looked very promising. Maybe you can bring out a fixed version after the contest?

You should be able to force it through with the automate function. (Poison will also work, but you need to poison yourself multiple times).
I'll be reworking the backend to make it easier to update and debug, so I'm trying to decide if I want to push the fixed version right away or if I want to wait for the backend rework to be finished.
Note: once the backend rework is done, anyone on the current version will need to use the version updater in order to fix their save file; otherwise there may be some serious instability.
