Hi Berry, thank you for playing! We appreciate the valuable feedback and glad you had fun!
We didn't think about switching 1/2 keys, that's indeed more appropriate key bindings (although you can self-bind them in the settings menu), we will consider this into upcoming updates.
Regarding the freezers, we don't expect players to open each and every one of them, the journal notes tell you exactly which one should be occupied, we did an awful job of explaining the importance of reading through the journal notes, and it's already fixed and will be better explained in the upcoming update 3 days away.
We took notes of the rest of your feedback, thank you for taking the time to play. :)
